An adult female client with chronic kidney disease (CKD) asks the nurse if she can continue taking over-the-counter medications. Which medication provides the greatest threat to this client?

A. Magnesium hydroxide (Maalox).

B. Birth control pills.

C. Cough syrup containing codeine.

D. Cold medication containing alcohol.

Correct Answer: A
Rationale: The correct answer is A: Magnesium hydroxide (Maalox). In clients with CKD, magnesium can accumulate to toxic levels due to decreased excretion by the kidneys. Therefore, it poses the greatest threat to this client population. Choice B, birth control pills, is not typically contraindicated in CKD. Choice C, cough syrup containing codeine, may require dose adjustments but is not the greatest threat. Choice D, cold medication containing alcohol, is a concern mainly in liver disease, not CKD.

While taking vital signs, a critically ill male client grabs the nurse's hand and asks the nurse not to leave. What action is best for the nurse to take?

• A. Pull up a chair and sit beside the client's bed.
• B. Reassure the client that you will return shortly.
• C. Ask another nurse to stay with the client.
• D. Continue taking vital signs and then leave the room.

Correct Answer: A
Rationale: The best action for the nurse to take in this situation is to pull up a chair and sit beside the client's bed. By doing so, the nurse can provide emotional support and comfort to the critically ill patient who is feeling vulnerable. Sitting with the client also shows empathy and a willingness to listen to the client's needs. Reassuring the client that the nurse will return shortly (Choice B) may not address the immediate need for emotional support. Asking another nurse to stay with the client (Choice C) may not establish the same level of connection and comfort as sitting with the client personally. Continuing to take vital signs and then leaving the room (Choice D) disregards the client's emotional needs in that moment.

While caring for a toddler receiving oxygen (02) via face mask, the nurse observes that the child's lips and nares are dry and cracked. Which intervention should the nurse implement?

• A. Ask the mother what she usually uses on the child's lips and nose.
• B. Apply a petroleum jelly (Vaseline) to the child's nose and lips.
• C. Use a topical lidocaine (Zylocaine viscous) analgesic for cracked lips.
• D. Use a water-soluble lubricant on affected oral and nasal mucosa.

Correct Answer: D
Rationale: A water-soluble lubricant is safe to use in conjunction with oxygen therapy, unlike petroleum jelly which is flammable.

A client with end-stage renal disease (ESRD is scheduled for hemodialysis. Which laboratory value should the nurse monitor closely before the procedure?

• A. Serum creatinine
• B. Serum potassium
• C. Serum sodium
• D. Hemoglobin

Correct Answer: B
Rationale: Before hemodialysis in a client with end-stage renal disease (ESRD), monitoring serum potassium closely is crucial. ESRD patients are at risk of hyperkalemia, which can lead to severe cardiac complications. Checking serum potassium levels helps in assessing and managing this electrolyte imbalance. Serum creatinine (Choice A) is a marker of kidney function but is not the most critical value to monitor before hemodialysis. Serum sodium (Choice C) may be affected in renal disease, but potassium is a more crucial electrolyte to monitor. Hemoglobin (Choice D) is essential for assessing anemia in ESRD but is not the primary focus before hemodialysis.

A male client with ulcerative colitis received a prescription for a corticosteroid last month, but because of the side effects, he stopped taking the medication 6 days ago. Which finding warrants immediate intervention by the nurse?

• A. Anxiety and restlessness
• B. Increased bowel movements
• C. Abdominal cramping
• D. Fever and chills

Correct Answer: A
Rationale: The correct answer is A: Anxiety and restlessness. Abruptly stopping corticosteroids can cause adrenal insufficiency, leading to symptoms such as anxiety and restlessness. These symptoms indicate a potential serious complication that requires immediate intervention. Increased bowel movements and abdominal cramping are common side effects of ulcerative colitis and may not warrant immediate intervention. Fever and chills are not typically associated with adrenal insufficiency caused by corticosteroid withdrawal.
