A client with a history of chronic heart failure is admitted with shortness of breath and crackles in the lungs. Which laboratory value should be closely monitored?

A. Serum creatinine of 2.0 mg/dL

B. Serum sodium of 135 mEq/L

C. Serum potassium of 5.5 mEq/L

D. Blood glucose of 150 mg/dL

Correct Answer: C
Rationale: A serum potassium level of 5.5 mEq/L should be closely monitored in a client with chronic heart failure as it may indicate hyperkalemia, requiring intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias in patients with heart failure. Serum creatinine (Choice A) is important to monitor for kidney function but is not the priority in this case. Serum sodium (Choice B) and blood glucose (Choice D) levels are not typically the primary focus when assessing a client with heart failure presenting with respiratory symptoms and crackles in the lungs.

A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which laboratory value is most concerning?

• A. Serum potassium of 6.5 mEq/L
• B. Serum sodium of 135 mEq/L
• C. Serum creatinine of 2.0 mg/dl
• D. Blood glucose of 150 mg/dl

Correct Answer: A
Rationale: A serum potassium level of 6.5 mEq/L is concerning in a client with CKD as it indicates hyperkalemia, which requires immediate intervention to prevent cardiac complications. Hyperkalemia can lead to life-threatening arrhythmias, particularly in patients with impaired kidney function. Serum sodium, creatinine, and blood glucose levels, while important, are not as acutely dangerous as severe hyperkalemia in this context.

What is the most important instruction for the nurse to provide a client being discharged following treatment for Guillain-Barre syndrome?

• A. Avoid exposure to respiratory infections.
• B. Use relaxation exercises when anxious.
• C. Continue physical therapy at home.
• D. Plan short, frequent rest periods.

Correct Answer: A
Rationale: The most critical instruction for a client being discharged following treatment for Guillain-Barre syndrome is to avoid exposure to respiratory infections. Guillain-Barre syndrome can affect the respiratory system, making infections particularly dangerous. While relaxation exercises, physical therapy, and rest periods are beneficial for overall well-being and recovery, preventing respiratory infections takes precedence due to the potential life-threatening complications associated with respiratory compromise in Guillain-Barre syndrome.

A gravida 2 para 1, at 38-weeks gestation, scheduled for a repeat cesarean section in one week, is brought to the labor and delivery unit complaining of contractions every 10 minutes. While assessing the client, the client's mother enters the labor suite and says in a loud voice, 'I've had 8 children and I know she's in labor. I want her to have her cesarean section right now!' What action should the nurse take?

• A. Tell the mother to stop speaking for the client.
• B. Notify the charge nurse of the situation.
• C. Request that the mother leave the room.
• D. Request security to remove her from the room.

Correct Answer: C
Rationale: In this scenario, the most appropriate action for the nurse to take is to request that the mother leave the room. This is important to maintain a calm environment and allow the healthcare team to assess and manage the situation without interference. Option A is not the best choice as it may escalate the situation. Option B, notifying the charge nurse, could be considered after addressing the immediate need to remove the mother from the room. Option D, requesting security to remove her, is not necessary at this point and may further escalate the situation unnecessarily.

The nurse determines that a client's pupils constrict as they change focus from a far object. What documentation should the nurse enter about this finding?

• A. Pupils reactive to accommodation.
• B. Nystagmus present with pupillary focus.
• C. Peripheral vision intact.
• D. Consensual pupillary constriction present.

Correct Answer: A
Rationale: The correct answer is A: 'Pupils reactive to accommodation.' When pupils constrict as the client changes focus from a far object to a near one, it indicates a normal response known as accommodation. This physiological process allows the eyes to adjust their focus, and it is a healthy finding. Choice B is incorrect because nystagmus is an involuntary eye movement, not related to the change in focus. Choice C is irrelevant to the scenario and does not describe the observed finding. Choice D refers to pupillary constriction in response to light, not accommodation to changes in focus.
