Anaphylactic shock is a subgroup of which type of shock?
Hypovolemic
Obstructive
Cardiogenic
Distributive
The Correct Answer is D
Choice A rationale:
Hypovolemic shock is a type of shock that occurs when there is a significant loss of blood or fluid volume, leading to decreased cardiac output and tissue perfusion. This can be caused by severe bleeding, dehydration, burns, or other conditions that result in fluid loss. While anaphylaxis can involve some fluid shifts, it is not primarily characterized by a loss of blood or fluid volume.
Key features of hypovolemic shock that distinguish it from anaphylactic shock include:
Prominent signs of dehydration: Dry skin and mucous membranes, decreased urine output, sunken eyes, and poor skin turgor.
Hemodynamic changes: Tachycardia, narrow pulse pressure, and cold extremities due to vasoconstriction to maintain blood pressure.
Laboratory findings: Elevated hematocrit and blood urea nitrogen (BUN) levels, indicating hemoconcentration and decreased kidney perfusion.
Choice B rationale:
Obstructive shock is a type of shock that occurs when there is an obstruction to blood flow, preventing adequate circulation to the body's tissues. This can be caused by conditions such as pulmonary embolism, cardiac tamponade, or tension pneumothorax. Anaphylaxis does not involve a physical obstruction to blood flow.
Key features of obstructive shock that distinguish it from anaphylactic shock include:
Evidence of the underlying obstruction: Jugular venous distension (cardiac tamponade), muffled heart sounds (cardiac tamponade), or respiratory distress (pulmonary embolism or tension pneumothorax).
Distinctive hemodynamic changes: Equalization of diastolic pressures between the right and left ventricles (cardiac tamponade).
Specific imaging findings: Enlarged cardiac silhouette on chest X-ray (pericardial effusion), filling defects in the pulmonary arteries on CT angiography (pulmonary embolism), or hyperexpanded lung fields with a deviated trachea on chest X-ray (tension pneumothorax).
Choice C rationale:
Cardiogenic shock is a type of shock that occurs when the heart is unable to pump enough blood to meet the body's needs. This can be caused by conditions such as heart attack, heart failure, or cardiomyopathy. Anaphylaxis does not primarily involve a failure of the heart's pumping function.
Key features of cardiogenic shock that distinguish it from anaphylactic shock include:
Evidence of heart failure: Pulmonary edema, elevated jugular venous pressure, and a third heart sound (S3 gallop).
Electrocardiogram (ECG) changes: ST-segment elevation or depression, Q waves, or other signs of myocardial ischemia or infarction.
Elevated cardiac enzymes: Troponin and creatine kinase-MB (CK-MB) levels, indicating heart muscle damage.

Correct Answer is A
Explanation
Choice A rationale:
Paralytic ileus is a common postoperative complication that occurs when the normal movement of the intestines (peristalsis) is slowed or stopped. This can lead to a buildup of gas and fluids in the intestines, causing abdominal distention, nausea, vomiting, and constipation. The absence of bowel sounds, abdominal distention, and the inability to pass flatus are all classic signs of paralytic ileus.
Here are some of the factors that can contribute to paralytic ileus: Manipulation of the intestines during surgery
Anesthesia
Pain medications, especially opioids Electrolyte imbalances
Dehydration
Underlying medical conditions, such as diabetes or kidney disease Treatment for paralytic ileus typically involves:
Resting the bowel by not eating or drinking anything by mouth
Using a nasogastric (NG) tube to suction out gas and fluids from the stomach Providing intravenous (IV) fluids and electrolytes
Encouraging early ambulation
Using medications to stimulate bowel movement, such as metoclopramide or erythromycin
Choice B rationale:
Incisional infection is an infection of the surgical wound. It would typically present with redness, warmth, swelling, and pain at the incision site. The patient may also have a fever. While incisional infections can occur after abdominal surgery, they are not typically associated with the absence of bowel sounds, abdominal distention, and the inability to pass flatus.
Choice C rationale:
Fecal impaction is a severe form of constipation in which a large, hard mass of stool becomes trapped in the rectum. It can cause abdominal pain, bloating, and difficulty passing stool. However, it is not typically associated with the absence of bowel sounds or abdominal distention.
Choice D rationale:
Health care-associated Clostridium difficile (C. difficile) is a bacterial infection that can cause severe diarrhea, abdominal pain, and cramping. It is often associated with antibiotic use. While C. difficile can occur after abdominal surgery, it is not typically associated with the absence of bowel sounds, abdominal distention, and the inability to pass flatus.
Correct Answer is C
Explanation
Choice A rationale:
This response is dismissive of the patient's pain and does not offer any assistance. It also does not acknowledge the patient's concerns about their pain being a normal part of aging.
It's important to validate the patient's experience and offer support, even if the pain level is not severe.
This response could lead to the patient feeling unheard and unsupported, and it could potentially delay necessary treatment.
Choice B rationale:
This response suggests that the patient's pain is not significant enough to warrant treatment unless it worsens. This is not appropriate, as pain is subjective and should be treated based on the patient's individual experience.
Additionally, this response reinforces the patient's belief that pain is a normal part of aging, which may prevent them from seeking treatment in the future.
Choice C rationale:
This response is the best option because it acknowledges the patient's pain, expresses concern, and suggests further investigation.
It is important to rule out any underlying medical conditions that may be causing the pain.
This response also demonstrates to the patient that the nurse is taking their pain seriously and is committed to helping them manage it.
Choice D rationale:
This response acknowledges that pain can be a part of aging, but it also suggests that there may be a specific cause for the patient's pain.
This could lead to the patient feeling anxious or worried about their health.
It is important to investigate the cause of the pain before making any assumptions.
