Correct Answer: A

Rationale: The nurse would most likely suspect fungi as the cause of thickened and separated toenails. Fungal infections can lead to changes in the nail structure, causing them to thicken and separate from the nail bed. Friction, nail polish, and nail polish remover are less likely to cause these specific nail changes. Friction typically leads to calluses or blisters, while nail polish and nail polish remover do not commonly result in thickened and separated toenails.

Correct Answer: D

Rationale: During a patient assessment, critical thinking is a priority because a patient's condition can change rapidly, necessitating continuous critical thinking and adaptation of nursing interventions. While foot care, daily bathing, and hygiene needs are important components of patient care, they may not always take precedence over critical thinking, which guides the nurse in making timely and appropriate decisions based on the patient's current condition and needs. Therefore, critical thinking stands out as the most crucial principle during patient assessments.

Correct Answer: A

Rationale: Avocados are a good choice to suggest adding to the diet of a client with hypercholesterolemia because they are high in healthy fats, particularly monounsaturated fats, which can help manage cholesterol levels. On the other hand, fried chicken, whole milk, and bacon are high in saturated fats and cholesterol, which should be limited in a diet aimed at managing hypercholesterolemia. Therefore, choices B, C, and D are incorrect.

Correct Answer: A

Rationale: The correct answer is A: Pain related to ischemia. This nursing diagnosis should have priority because addressing the pain caused by ischemia is crucial in managing the client's myocardial infarction. Pain management is essential not only for the client's comfort but also for improving outcomes and reducing complications. Choices B, C, and D are not the priority in this scenario. Risk for altered elimination: constipation (Choice B) is not as immediate a concern as managing the client's pain. Risk for complication: dysrhythmias (Choice C) may be a potential concern but addressing the client's pain takes precedence. Anxiety related to pain (Choice D) is important to address but should come after managing the pain itself.
