Choice A rationale

The client's fundus is boggy and elevated above the umbilicus, deviating to the right, which indicates uterine atony. This, coupled with the saturated perineal pad and voiding of only 50 mL of urine initially, followed by 700 mL of pink-tinged urine after catheterization, suggests significant blood loss. These findings are classic signs of postpartum hemorrhage, which is often caused by uterine atony preventing effective uterine contraction and vessel compression. Normal postpartum fundal height should decrease daily.

Choice B rationale

Postpartum infection, such as puerperal sepsis, typically presents with fever, chills, uterine tenderness, and foul-smelling lochia. While the client is experiencing discomfort, there is no mention of fever or purulent discharge. The primary signs observed relate to excessive bleeding and uterine displacement, not infectious processes. A normal temperature range is 36.5°C to 37.5°C (97.7°F to 99.5°F).

Choice C rationale

Endometritis is an infection of the uterine lining, often occurring postpartum. Symptoms include fever, lower abdominal pain, uterine tenderness, and foul-smelling lochia. The client's symptoms of a boggy fundus, heavy bleeding, and fundal deviation are more indicative of a bleeding issue rather than an infection confined to the endometrium. White blood cell count would typically be elevated in infection, with a normal range being 4,500 to 11,000 cells/mm³.

Choice D rationale

A urinary tract infection (UTI) is characterized by dysuria, urgency, frequency, and sometimes hematuria. While the client reports an urge to urinate and voided a small amount, the primary and more concerning findings are related to the uterine status and excessive bleeding, which are not typical signs of a UTI. A urine culture would show bacterial growth in a UTI, with a normal urinalysis showing no or few bacteria.

Choice E rationale

Uterine inversion is a rare but severe complication where the uterus turns inside out, often presenting with sudden, severe pain, vaginal hemorrhage, and a mass protruding from the vagina. While hemorrhage is present, the description of the fundus being boggy and 2 finger breaths above the umbilicus, rather than inverted or prolapsed, makes uterine inversion less likely. The primary issue is uterine atony leading to blood loss.

Choice C rationale

The client is tachycardic and has cool skin, indicating potential hypovolemia or shock due to excessive bleeding. Administering oxygen at 2 L/min via nasal cannula increases oxygen delivery to the tissues, improving cellular oxygenation and mitigating the effects of decreased circulating blood volume. This supports vital organ function and helps address tissue hypoxia, a common consequence of significant blood loss. Normal heart rate postpartum is 60-100 beats per minute.

Choice D rationale

Oxytocin is a uterotonic agent that stimulates uterine contractions. A boggy uterus and excessive bleeding are hallmark signs of uterine atony, the most common cause of postpartum hemorrhage. Initiating an infusion of oxytocin will promote uterine contraction, which compresses blood vessels and reduces blood loss, thereby addressing the underlying cause of the client's symptoms and preventing further hemorrhage. Normal lochia should be moderate in amount.

Choice A rationale

Patterned breathing techniques involve conscious control of respiratory rate and depth, which can redirect attention and promote relaxation. This cognitive distraction reduces the perception of pain by engaging higher cortical centers, thus modulating pain signals transmitted via the spinothalamic tracts. However, it does not directly address the localized pressure associated with back labor.

Choice B rationale

Effleurage involves light, circular stroking of the abdomen. This gentle cutaneous stimulation activates large-diameter afferent nerve fibers, which, according to the gate control theory of pain, can inhibit the transmission of noxious stimuli by smaller-diameter fibers in the spinal cord. While soothing, it may not provide sufficient counter-pressure for intense back labor.

Choice C rationale

Sacral counterpressure involves applying firm, sustained pressure to the sacrum. This technique directly opposes the pressure exerted by the fetal occiput against the sacral nerves during back labor. The deep pressure stimulates mechanoreceptors, which can significantly reduce the perception of pain through afferent inhibition and potentially alter the biomechanics of fetal descent.

Choice D rationale

Guided imagery involves directing the client to focus on pleasant mental images to divert attention from pain. This cognitive behavioral strategy can activate descending inhibitory pathways from the brainstem, releasing endogenous opioids and serotonin, thereby modulating pain perception. However, it may not be as effective for the specific, intense pressure of back labor.

Choice A rationale

Placing the newborn under a radiant warmer is crucial for thermoregulation, preventing cold stress, which can lead to increased metabolic rate and oxygen consumption. While important, assessing for potential airway compromise due to meconium aspiration takes immediate precedence over maintaining temperature, as respiratory status is critical for survival.

Choice B rationale

Providing tactile stimulation can encourage respiratory effort in a depressed newborn. However, in the presence of meconium-stained amniotic fluid, initial assessment of the airway and the need for suctioning must occur before stimulating the newborn to breathe deeper, which could potentially draw meconium further into the lungs.

Choice C rationale

When meconium-stained amniotic fluid is present, the primary concern is meconium aspiration syndrome. Determining if the mouth and nose require bulb suctioning is the first action to clear any meconium from the upper airway, preventing its aspiration into the lungs upon the newborn's first breaths, thereby mitigating respiratory distress.

Choice D rationale

Initiating skin-to-skin contact promotes maternal-newborn bonding and can stabilize the newborn's temperature and blood glucose. While beneficial, it is not the immediate priority when meconium is present. Airway management and respiratory stabilization must be ensured before initiating skin-to-skin contact to prevent complications from meconium aspiration.

Choice A rationale

In the scenario of ruptured membranes with a breech presentation, there is an elevated risk of umbilical cord prolapse due to the disproportionate fit of the presenting part in the maternal pelvis. Checking fetal heart tones immediately allows for rapid detection of cord compression, which manifests as abrupt decelerations, indicating fetal distress and necessitating urgent intervention.

Choice B rationale

While a cesarean birth is often indicated for breech presentations, especially with ruptured membranes, it is not the immediate first action. The priority is to assess fetal well-being, specifically ruling out umbilical cord prolapse, as this is an acute emergency that requires immediate intervention to prevent fetal hypoxia and mortality, prior to surgical preparation.

Choice C rationale

Assessing the color, amount, and odor of the amniotic fluid provides information about potential infection or meconium presence, which are important data points. However, the immediate life-threatening complication with ruptured membranes and breech presentation is umbilical cord prolapse, making fetal heart tone assessment a more urgent priority.

Choice D rationale

Performing a Nitrazine test confirms the rupture of membranes, but the client has already reported "my water just broke.”. While a confirmatory test, it is not the immediate priority. The critical concern is the potential for umbilical cord prolapse, which directly impacts fetal oxygenation and requires immediate assessment via fetal heart tones.

Choice A rationale

A client with an indwelling urinary catheter is at increased risk for falls due to several factors. The catheter tubing can create a tripping hazard, and the associated bag can restrict mobility. Furthermore, the presence of a catheter can lead to postural hypotension upon ambulation due to prolonged bedrest or fluid shifts, impairing balance and increasing fall risk.

Choice B rationale

A second-degree perineal laceration causes localized pain and discomfort, potentially leading to a cautious gait. While this can affect mobility, it does not inherently present the same level of tripping hazard or systemic physiological changes like orthostatic hypotension that are associated with an indwelling catheter, making the fall risk comparatively lower.

Choice C rationale

Saturating a perineal pad every 5 to 6 hours indicates a normal lochial flow. Excessive bleeding (saturating a pad in less than an hour) would be a significant risk factor for hypovolemia and subsequent orthostatic hypotension, thus increasing fall risk. Normal flow, however, does not directly contribute to an increased fall risk.

Choice D rationale

Breast engorgement causes discomfort and fullness in the breasts, which can limit arm movement and potentially interfere with comfortable positioning. While uncomfortable, breast engorgement itself does not typically lead to systemic physiological changes like orthostatic hypotension or create physical impediments that directly increase the risk of a fall.

Choice A rationale

Consuming milk with iron supplements significantly inhibits iron absorption due to the high calcium content in milk. Calcium competes with iron for absorption sites in the small intestine, forming insoluble complexes that reduce the bioavailability of iron. This would counteract the intended therapeutic effect of the iron supplementation, leading to suboptimal iron levels.

Choice B rationale

Doubling an iron dose can lead to iron toxicity, which is dangerous, especially during pregnancy. Excessive iron intake can cause gastrointestinal distress, liver damage, and metabolic acidosis. Adhering to the prescribed dosage is crucial for safe and effective supplementation, preventing adverse effects while achieving therapeutic iron levels.

Choice C rationale

Maintaining adequate fiber intake (normal range 25-30 grams daily) is crucial during iron supplementation. Iron often causes constipation due to its effect on gastrointestinal motility. Dietary fiber adds bulk to stool, promoting regular bowel movements and alleviating constipation, which is a common and uncomfortable side effect of iron therapy.

Choice D rationale

Vitamin K is essential for blood coagulation, but taking 100 milligrams daily during pregnancy without a specific medical indication is excessive and potentially harmful. The normal recommended daily allowance for vitamin K during pregnancy is much lower, around 90 micrograms. High doses could interfere with anticoagulant medications or have unknown fetal effects.

Choice A rationale

During labor, the body experiences physiological stress and an inflammatory response, leading to an increase in white blood cell count. This leukocytosis is a normal physiological adaptation to the physical demands of labor and tissue remodeling, not a decrease. A normal WBC count is typically 4,500-11,000 cells/µL, and it can rise to 15,000-20,000 cells/µL during labor.

Choice B rationale

Labor is an energy-intensive process that increases metabolic demands, leading to greater glucose utilization by uterine muscles and other tissues. This increased consumption of glucose can result in a decrease in blood glucose levels as the body expends energy to fuel contractions and other physiological activities. A normal blood glucose range is 70-100 mg/dL.

Choice C rationale

The pain and physiological stress of labor typically cause an increase in respiratory rate, not a decrease. The body tries to compensate for the increased metabolic demand and oxygen consumption by increasing ventilation. A decrease in respiratory rate would be an unexpected and potentially concerning finding, indicating respiratory depression. A normal respiratory rate is 12-20 breaths per minute.

Choice D rationale

While slight fluctuations can occur, a significant decrease in temperature is not an expected finding during labor. The metabolic activity and physical exertion of labor can slightly elevate body temperature, or it may remain stable. A decrease in temperature could indicate hypothermia or a systemic issue, which is not a normal physiological response to labor. A normal temperature is 36.5-37.5°C.

Choice A rationale

Tachycardia is a common finding in hyperemesis gravidarum due to fluid volume deficit. Significant and persistent vomiting leads to hypovolemia, which triggers a compensatory increase in heart rate to maintain cardiac output and tissue perfusion. The body attempts to compensate for reduced circulating blood volume by increasing the rate at which blood is pumped.

Choice B rationale

Dry mucous membranes are a direct clinical sign of dehydration, which is a hallmark of hyperemesis gravidarum. Prolonged and severe vomiting leads to significant fluid loss, depleting the body's water content. This desiccation is visibly manifested in the oral cavity as dry and sticky mucous membranes, indicating intracellular and extracellular fluid deficit.

Choice C rationale

Poor skin turgor, characterized by skin that remains tented when pinched, is another objective indicator of dehydration. The loss of interstitial fluid due to excessive vomiting reduces the elasticity and plumpness of the skin. This finding reflects a significant depletion of fluid volume within the subcutaneous tissues.

Choice D rationale

Polyuria, meaning excessive urination, is not a typical finding in hyperemesis gravidarum. Instead, severe vomiting and dehydration would lead to oliguria (decreased urine output) as the kidneys attempt to conserve fluid to compensate for the significant fluid losses. The body's priority is fluid retention.

Choice E rationale

Hypertension is generally not associated with hyperemesis gravidarum. Due to significant fluid loss and dehydration, clients with hyperemesis gravidarum are more likely to experience orthostatic hypotension or even profound hypotension as a result of hypovolemia. The decreased circulating blood volume leads to reduced vascular resistance and blood pressure.

Choice A rationale

Monitoring blood pressure every 30 minutes following epidural placement is insufficient. Epidural anesthesia often causes sympathetic blockade, leading to vasodilation and a rapid drop in blood pressure. Frequent monitoring, typically every 2-5 minutes initially, is critical to detect and manage hypotension promptly, ensuring adequate placental perfusion.

Choice B rationale

Administering a lactated Ringer's 500 mL bolus intravenously prior to epidural placement is a crucial prophylactic measure. This fluid bolus expands intravascular volume, counteracting the vasodilation and subsequent hypotension that can occur with sympathetic blockade from epidural anesthesia, thereby maintaining maternal blood pressure and placental perfusion.

Choice C rationale

Administering oxygen via nasal cannula at 2 L/min prior to epidural placement is generally not indicated as a routine prophylactic measure. Oxygen supplementation is typically reserved for instances where maternal oxygen saturation is low or there is fetal distress, not as a standard pre-epidural intervention for normoxic clients.

Choice D rationale

Repositioning the client every 2 hours following epidural placement is not frequent enough. To promote even distribution of the anesthetic and prevent prolonged pressure on specific areas, the client should be repositioned more frequently, typically every 30-60 minutes, from side to side, especially during active labor.
