1. A nurse is reviewing the laboratory results for a client who has Cushing's disease. The nurse should expect the client to have an increase in which of the following laboratory values?

Correct answer: A

Rationale: The correct answer is A: Serum glucose level. In Cushing's disease, there is an excess production of cortisol, leading to hyperglycemia. This results in an increase in serum glucose levels. Choices B, C, and D are incorrect because Cushing's disease does not directly affect serum calcium levels, lymphocyte count, or serum potassium levels.

2. Which nursing action is a priority when managing a client with a wound infection?

Correct answer: B

Rationale: Performing a wound culture before administering antibiotics is crucial when managing a client with a wound infection. This step helps identify the specific pathogens causing the infection, allowing for the prescription of the most effective antibiotics. Changing the wound dressing every 24 hours (Choice A) is important for wound care but not the priority when an infection is present. Cleansing the wound with alcohol-based solutions (Choice C) can be too harsh and may delay wound healing. Applying a wet-to-dry dressing (Choice D) is not recommended for infected wounds as it can cause trauma to the wound bed during dressing changes.

3. A nurse is providing teaching to an older adult client about methods to promote nighttime sleep. Which of the following instructions should the nurse include?

Correct answer: A

Rationale: The correct answer is to instruct the older adult client to eat a light snack before bedtime. This is beneficial as it helps prevent hunger, which can disrupt sleep. Choice B is incorrect as staying in bed for a prolonged time if unable to fall asleep can lead to frustration and worsen insomnia. Choice C is incorrect as taking a 1-hour nap during the day can interfere with the ability to fall asleep at night. Choice D is incorrect as performing exercises prior to bedtime can increase alertness and make it harder to fall asleep.

4. A client receiving chemotherapy has developed stomatitis. Which of the following actions should the nurse take?

Correct answer: B

Rationale: The correct action for the nurse to take when caring for a client with stomatitis due to chemotherapy is to encourage the client to eat soft foods. Soft foods help prevent further irritation to the already inflamed and sore oral mucosa. Providing lemon-glycerin swabs may further irritate the mucosa due to the acidic nature of lemon. Avoiding toothpaste is advisable as many toothpaste products contain ingredients that can aggravate stomatitis. Instructing the client to use a mouthwash containing alcohol is contraindicated as alcohol-based mouthwashes can be too harsh and drying for the already sensitive oral tissues.

5. A client is being taught about taking warfarin to treat atrial fibrillation. Which of the following statements by the client indicates an understanding of the teaching?

Correct answer: B

Rationale: The correct answer is B because taking warfarin later on the same day if a dose is missed helps maintain therapeutic levels. Choice A is incorrect because warfarin should be taken with food to enhance absorption. Choice C is incorrect as skipping a dose can lead to fluctuations in warfarin levels. Choice D is incorrect as taking an additional dose can increase the risk of bleeding.
