Correct Answer: A

Rationale: Pharyngeal diphtheria is transmitted via droplets, primarily through respiratory secretions. Therefore, droplet precautions are necessary to prevent the spread of the infection. Droplet precautions involve wearing a surgical mask, goggles, and a gown when within three feet of the client. Contact precautions are used for diseases transmitted by direct or indirect contact; airborne precautions are for diseases transmitted through airborne particles; protective precautions are not a standard precaution type.

Correct Answer: D

Rationale: When a nurse observes peristomal skin irritation while changing a client's colostomy pouch, it is crucial to ensure that the pouch is slightly larger (0.32 cm or 1/8 inch) than the stoma. This extra space helps prevent the pouch from rubbing against the stoma and causing further irritation. Option A is correct because colostomy pouches should be changed based on individual needs, not necessarily every 24 hours. Option B is incorrect because applying the pouch only when the skin barrier is completely dry ensures better adhesion. Option C is incorrect as patting the peristomal skin dry after cleaning is more gentle and less likely to cause irritation compared to rubbing.

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: 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: D

Rationale: The correct action for external rotation of the shoulder involves moving the patient's arm until the thumb is upward and lateral to the head with the elbow flexed. This position maximizes external rotation at the shoulder joint. Choices A, moving the arm in a full circle, B, moving the arm across the body, and C, moving the arm behind the body with the elbow straight, do not describe external rotation and are incorrect. Therefore, Choice D is the correct action for performing external rotation.
