Correct Answer: A

Rationale: Being aware of cultural differences is crucial because normal behaviors in one culture may be perceived as deviant, immoral, or insane in another. This awareness helps the nurse avoid misunderstandings or misinterpretations of behaviors that are considered acceptable in the client's cultural context but may be viewed differently in another. Choices B, C, and D are incorrect because understanding cultural issues goes beyond deriving meanings from conventional wisdom, personal values guiding interactions, or relying solely on knowledge of developmental mental stages.

Correct Answer: B

Rationale: A decrease in white blood cell count indicates that the infection is responding to treatment and the client's condition is improving. Monitoring the white blood cell count is a more objective indicator of the body's response to the antibiotics. Choices A, C, and D may also be positive signs, but they are less specific and may vary among individuals. Respiratory rate alone may not be sufficient to indicate improvement, as other factors can influence it. Energy levels and cough characteristics are subjective and may not always correlate with the effectiveness of antibiotic treatment.

Correct Answer: C

Rationale: The correct answer is to advise the client to apply ice to the breasts for comfort. Applying ice can help reduce swelling and discomfort associated with engorgement in a woman who is not breastfeeding. Expressing milk manually would stimulate further milk production, which is not desired in this case. Wearing a tight bra could increase discomfort by putting pressure on the engorged breasts. Warm showers may actually increase swelling due to the vasodilation effect of heat.

Correct Answer: B

Rationale: The correct answer is B. Alendronate (Fosamax) should be taken with a full glass of water in the morning to prevent esophageal irritation and ensure proper absorption. Choice A is incorrect because taking alendronate at bedtime increases the risk of esophageal irritation due to lying down. Choice C is incorrect because patients should remain upright for at least 30 minutes after taking alendronate to prevent esophageal irritation. Choice D is incorrect because alendronate should be taken on an empty stomach, not with food, to enhance absorption.

Correct Answer: B

Rationale: The correct answer is to perform a quick assessment of the client's condition when the high-pressure alarm goes off on the ventilator. This assessment is crucial to determine the cause of the alarm and the client's current status. Option A is incorrect because disconnecting the client from the ventilator without assessing the situation can be harmful. Option C is incorrect as the nurse should first assess the client before seeking additional help. Option D is incorrect because resetting the alarm without understanding the underlying issue may lead to potential risks to the client.
