Correct Answer: A

Rationale: Pressure ulcers usually occur over bony prominences and are caused by decreased circulation. The client who is left in one position in bed for extended periods of time is more prone to decreased circulation to an area of the body and to acquiring a pressure ulcer. Choices B and C are incorrect as pressure ulcers are not exclusive to underweight or overweight clients. The key factor is prolonged pressure on the skin, not the weight of the client. Therefore, the correct answer is that pressure ulcers are most likely to occur when clients are immobilized in one position for extended periods of time.

Correct Answer: D

Rationale: The correct answer is developing interventions for grief and loss. In this scenario, the client's pain is not solely sensory but also affective due to grieving over the death of their spouse. It is essential to address the emotional component of pain by providing support and interventions for grief and loss. Referring the client for a psychiatric consult may not be necessary as grieving is a normal response to such a significant loss. Calling the physician for an increased dosage of pain medication or a sedative solely focuses on the sensory aspect of pain and does not address the underlying emotional distress.

Correct Answer: D

Rationale: Gentle bubbling is a normal finding for a client with a pleural drainage system to suction, so it simply needs to be documented for monitoring purposes. If the bubbling becomes vigorous, it could indicate a leak, which would then require further investigation by the nurse. Therefore, the correct action at this point is to document the finding. Notifying the physician is not necessary for gentle bubbling as it is expected. Clamping the chest tube or replacing the system is inappropriate and could potentially harm the client as there is no indication for such actions based on the scenario provided.

Correct Answer: D

Rationale: The recommended way to secure an infant in a car is to place them in the middle of the back seat in a rear-facing infant safety seat. Option A is incorrect because infants should never be held while in a moving vehicle due to safety concerns. Option B is incorrect because placing an infant in the front seat with a rear-facing safety seat can be risky if the car has passenger-side airbags. Option C is incorrect as booster seats are not suitable for infants. Therefore, the correct choice is to secure the infant in the middle of the back seat in a rear-facing infant safety seat.

Correct Answer: D

Rationale: The correct answer is infant rice cereal. Single-grain infant cereals are recommended as the first solid food because they are easily digestible and have added iron content. Choice C, yogurt, is incorrect because yogurt is a milk product and should be delayed until the child is 12 months old due to the risk of milk allergy. Choices A and B are incorrect because fruits and vegetables are typically introduced after cereals to help the infant get accustomed to solid foods gradually.
