Correct Answer: B

Rationale: The nurse should immediately obtain a Doppler device and recheck the pulses. The dorsalis pedis and posterior tibial pulses can be difficult to assess and might need to be verified with a Doppler device. Since the client just had surgery with a risk of arterial insufficiency, close monitoring is crucial. If pulses are not palpable, it indicates an emergent situation requiring immediate physician notification. Waiting 30 minutes before reassessment could lead to foot ischemia. While documenting findings is essential, it should follow pulse confirmation or necessary interventions to ensure the client's foot viability.

Correct Answer: A

Rationale: The correct answer is the 'structure of the health care system and family structure'. Scholars suggest that the reasons families are having difficulty providing health care for their members lie with both the structure of the health care system and the family structure. Major factors explaining differences in utilization patterns of medical services include the lack of healthcare insurance coverage, lack of services for special populations (such as teenage males), perception by families of the health care system and the health care provider, and lack of partnership between health care providers and families in mutually addressing health care issues. Choices B, C, and D are incorrect as they do not address the fundamental reasons related to the health care system and family structure as discussed in the provided extract.

Correct Answer: A

Rationale: Dry skin is also called xerosis. In this condition, the epidermis lacks moisture or sebum and is often marked by a pattern of fine lines, scaling, and itching. Xerosis is the correct term for very dry skin. Pruritus is the symptom of itching, an uncomfortable sensation that prompts the urge to scratch the skin, but it does not specifically refer to dry skin. Seborrhea is a skin condition characterized by overproduction of sebum, leading to excessive oiliness or dry scales, not necessarily indicating very dry skin. Actinic keratoses are sun-related skin lesions that are premalignant and not associated with dry skin.

Correct Answer: D

Rationale: The correct answer is that the client mixes their medications with their tube-feeding formula. Medications should not be mixed with tube-feeding formula or other medications as it may alter their effectiveness. The G-tube should be flushed before, between, and after the medications to prevent clogging and ensure proper administration. The client should remain in the Semi-Fowler's position for at least 30 minutes after medication administration to prevent reflux. Choice B is correct as it aligns with the proper post-administration positioning. Choices A and C are incorrect as flushing the G-tube before, between, and after medications, and mixing each medication separately in warm water are appropriate procedures that do not indicate a need for further instruction.

Correct Answer: B

Rationale: The correct answer is Osteoarthritis. Osteoarthritis is characterized by hard, nontender nodules of 2 to 3 mm or larger. These osteophytes (bony overgrowths) of the distal interphalangeal joints are called Heberden nodes. In this disorder, when these nodes occur on the proximal interphalangeal joints, they are called Bouchard nodes. Heberden nodes are not associated with scoliosis, rotator cuff lesions, or carpal tunnel syndrome. Therefore, choices A, C, and D are incorrect.
