The practical nurse (PN) is assisting the registered nurse (RN) in caring for a client with placenta previa who is at 31-weeks gestation.
Which method should the PN use to most accurately estimate blood loss?
Describe percentage of perineal pads saturated with blood.
Notify the laboratory to obtain an hourly hematocrit.
Evaluate changes in vital signs that might indicate shock.
Calculate the difference in weight of perineal pad before and after use.
The Correct Answer is D
Choice A rationale
Describing the percentage of saturated perineal pads is a subjective and imprecise method for estimating blood loss. Variations in pad size, absorbency, and the client's perception can lead to significant inaccuracies, making it unreliable for precise clinical assessment of hemorrhage.
Choice B rationale
While hematocrit levels are crucial for assessing overall blood volume status, obtaining an hourly hematocrit is an indirect and reactive measure of acute blood loss. It reflects hemodilution or hemoconcentration over time rather than providing a real-time, accurate quantification of the volume of blood lost. Normal hematocrit for pregnant women is 33% to 44%.
Choice C rationale
Changes in vital signs, such as tachycardia, hypotension, and tachypnea, are late indicators of significant blood loss and hypovolemic shock. Relying solely on vital signs means that a substantial amount of blood has already been lost before changes become apparent, making it an insensitive method for early detection and estimation.
Choice D rationale
Calculating the difference in weight of perineal pads before and after use provides a highly accurate objective measurement of blood loss. One gram of weight is approximately equivalent to one milliliter of blood, allowing for precise quantification and enabling timely and appropriate clinical interventions.

Correct Answer is A
Explanation
Choice A rationale
Propping a bottle can lead to several adverse outcomes for an infant. It increases the risk of aspiration, as the infant may not be able to control the milk flow adequately. It can also contribute to otitis media due to milk pooling in the eustachian tubes and is associated with dental caries, particularly bottle mouth syndrome, and impaired bonding.
Choice B rationale
Sharing the observation with the charge nurse without first addressing the issue directly with the mother is not the most immediate or appropriate action. The PN should first attempt to educate and guide the mother, as this is within the scope of practice for direct client care and education.
Choice C rationale
Asking the mother if she is too tired is speculative and may be perceived as judgmental, potentially creating a barrier to effective communication and education. The PN's role is to provide health education and guidance regarding safe infant feeding practices, focusing on the behavior rather than the mother's perceived fatigue.
Choice D rationale
While observing the infant's behavior during feeding is important for a comprehensive assessment, the immediate and most critical action is to intervene with the unsafe practice of bottle propping. Observing further without addressing the identified risk delays necessary education and intervention to ensure infant safety.
Correct Answer is D
Explanation
Choice A rationale
Giving prescribed digoxin and furosemide is part of the long-term management for cardiac conditions, but these medications do not provide immediate relief for an acute hypoxic spell. Digoxin improves cardiac contractility, and furosemide promotes fluid excretion, but their onset of action is not rapid enough for emergent situations.
Choice B rationale
Returning the child to bed and elevating the head of the bed might provide some comfort but does not directly address the underlying physiological cause of the hypoxic spell. Elevating the head of the bed may slightly improve respiratory effort but won't reverse cyanosis effectively.
Choice C rationale
Offering to play a board game with the child as a distraction does not address the physiological emergency of a hypoxic spell. Distraction may be helpful for anxiety but is not an intervention for cyanosis, tachypnea, and tachycardia, which require medical intervention.
Choice D rationale
Providing oxygen increases the available oxygen for gas exchange, and promoting the knee-chest position reduces venous return to the heart, thereby decreasing right-to-left shunting and improving pulmonary blood flow in conditions like Tetralogy of Fallot, which commonly presents with "squatting" and hypoxic spells.
