Correct Answer: A

Rationale: Monitoring the white blood cell count is crucial when a patient is undergoing chemotherapy for breast cancer. Chemotherapy can lead to neutropenia, a condition of low white blood cell count, which significantly increases the risk of infections. Monitoring white blood cell count helps healthcare providers intervene promptly to prevent severe infections. Hemoglobin level, while important in assessing oxygen-carrying capacity, is not the priority in this scenario. Serum creatinine and blood glucose levels are not directly impacted by chemotherapy for breast cancer.

Correct Answer: C

Rationale: The correct action for the nurse in this scenario is to engage the client in a discussion about their decision to leave and then prepare them for discharge. This approach allows the nurse to assess the client's current state, address concerns, and plan for a safe discharge. Option A is incorrect because it does not involve a therapeutic communication approach and may escalate the situation. Option B is incorrect as it places a condition on the client for release, which is not recommended in this situation. Option D is incorrect as it does not prioritize the client's autonomy and right to make decisions about their care.

Correct Answer: B

Rationale: The correct order of steps for this procedure is to first inject air into the NPH insulin bottle to prevent vacuum formation. After injecting air into the NPH insulin, the next step is to withdraw the correct dose of regular insulin from its bottle. This sequence ensures that the regular insulin is drawn after the NPH insulin, preventing contamination and ensuring accurate dosing. Therefore, choice B is correct. Choices A, C, and D are incorrect because air should be injected into the NPH insulin first, not the regular insulin, and the doses should be withdrawn in the appropriate order to maintain the integrity and potency of each insulin type.

Correct Answer: A

Rationale: In paralytic ileus, bowel sounds are typically absent or significantly reduced due to decreased motility of the intestines. This absence of bowel sounds is a key characteristic used in diagnosing paralytic ileus. Hyperactive bowel sounds are not expected in this condition as there is a lack of normal peristalsis. Normal bowel sounds would not be present in paralytic ileus, and hypoactive bowel sounds, which indicate decreased bowel motility, are more commonly associated with conditions like postoperative ileus or constipation, rather than paralytic ileus.

Correct Answer: D

Rationale: Encouraging additional oral intake of juices and water is the appropriate intervention in this scenario. Dark amber urine can indicate concentrated urine due to dehydration or other factors. By encouraging more fluids, the LPN/LVN can help dilute the urine, reducing the concentration of pigments causing the dark color. Providing additional coffee (Choice A) would not necessarily increase hydration and could potentially have a diuretic effect. Exchanging grape juice for cranberry juice (Choice B) does not address the core issue of hydration. Bringing additional fruit (Choice C) may provide some fluid, but encouraging specific fluids like juices and water would be more effective in diluting the urine.
