Correct Answer: B

Rationale: When a 5-month-old infant vomits multiple times, there is a risk of developing metabolic alkalosis due to the loss of stomach acid. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. It is caused by the loss of hydrogen ions from the body, often through vomiting. Metabolic acidosis (choice A) is unlikely in this scenario because it is more commonly associated with conditions like renal failure or diabetic ketoacidosis. Choice C, increased serum hemoglobin levels, is not typically a direct consequence of vomiting. Choice D, decreased serum potassium levels, may occur with vomiting but is not the primary concern when a patient is vomiting excessively.

Correct Answer: A

Rationale: Choosing option A, 'Let's talk about how the change in your job status will affect you,' is the most appropriate response in this scenario. By discussing how retirement might affect the client, the nurse can address the client's concerns and emotions about the impending change. Option B, 'Have you considered the financial implications of retirement?' is not the best response as it focuses solely on financial aspects and does not address the client's emotional readiness for retirement. Option C, 'What are your thoughts on retirement and how it may impact your life?' is more open-ended and may not address the immediate concerns of the client expressing uncertainty. Option D, 'Would you like to discuss potential activities you could engage in during retirement?' assumes the client is certain about retiring and focuses on activities rather than addressing the client's feelings of uncertainty.

Correct Answer: A

Rationale: In a client with paralytic ileus, absent bowel sounds with distention are expected due to decreased or absent bowel motility. This is a key characteristic of paralytic ileus, where the bowel is unable to contract and move contents along the digestive tract. Hyperactive bowel sounds (choice B) are more indicative of increased peristalsis, which is not typically seen in paralytic ileus. Normal bowel sounds (choice C) may not be present in a client with paralytic ileus. High-pitched bowel sounds (choice D) are not typically associated with paralytic ileus. Therefore, the correct assessment finding in this scenario is absent bowel sounds with distention.

Correct Answer: D

Rationale: Applying a hydrocolloid or foam dressing is the most effective treatment to promote healing for a Stage 2 skin ulcer. These dressings create a moist environment that supports healing and prevents further tissue damage. Option A (covering the wound with a dry dressing) can lead to drying out the wound bed, hindering healing. Option B (using hydrogen peroxide soaks) can be too harsh and may damage the surrounding healthy tissue. Option C (leaving the area open to dry) can delay healing as it does not provide the necessary moist environment for optimal wound healing.

Correct Answer: A

Rationale: Veracity involves telling the truth, a fundamental ethical principle in healthcare. In this scenario, the nurse demonstrates veracity by responding honestly when the client directly asks about her cancer diagnosis. Choice B is incorrect as avoiding discussing the diagnosis to prevent emotional distress does not align with veracity and transparency. Choice C is incorrect as providing a vague answer does not uphold the principle of truthfulness. Choice D is incorrect because promising to provide information only upon client request does not address the immediate question about the cancer diagnosis and lacks transparency.
