1. A patient with diabetes insipidus is admitted to the intensive care unit after a motor vehicle accident that resulted in head trauma and damage to the pituitary gland. Diabetes insipidus can occur when there is a decreased production of which of the following?

• A. ADH
• B. Estrogen
• C. Aldosterone
• D. Renin

Correct answer: A

Rationale: The correct answer is A: ADH. Diabetes insipidus is characterized by a deficiency in antidiuretic hormone (ADH), leading to excessive urine output and thirst. In this scenario, the head trauma and damage to the pituitary gland can result in decreased production or release of ADH. Estrogen (Choice B) is not directly related to diabetes insipidus. Aldosterone (Choice C) is a hormone that regulates sodium and potassium levels, not water balance like ADH. Renin (Choice D) is an enzyme involved in the regulation of blood pressure and fluid balance but not directly related to diabetes insipidus.

2. A nurse assesses a client who is experiencing an acid-base imbalance. The clients arterial blood gas values are pH 7.34, PaO2 88 mm Hg, PaCO2 38 mm Hg, and HCO3 19 mEq/L. Which assessment should the nurse perform first?

• A. . Cardiac rate and rhythm
• B. Skin and mucous membranes
• C. Musculoskeletal strength
• D. Level of orientation

Correct answer: A

Rationale:

3. You are caring for a patient admitted with a diagnosis of acute kidney injury. When you review your patients most recent laboratory reports, you note that the patients magnesium levels are high. You should prioritize assessment for which of the followin

• A. Diminished deep tendon reflexes
• B. Tachycardia
• C. Cool, clammy skin
• D. Acute flank pain

Correct answer: A

Rationale:

4. A newly graduated nurse is admitting a patient with a long history of emphysema. The new nurses preceptor is going over the patients past lab reports with the new nurse. The nurse takes note that the patients PaCO2 has been between 56 and 64 mm Hg for several months. The preceptor asks the new nurse why they will be cautious administering oxygen. What is the new nurses best response?

• A. The patients calcium will rise dramatically due to pituitary stimulation.
• B. Oxygen will increase the patients intracranial pressure and create confusion.
• C. Oxygen may cause the patient to hyperventilate and become acidotic.
• D. Using oxygen may result in the patient developing carbon dioxide narcosis and hypoxemia.

Correct answer: D

Rationale:

5. A patient is taking spironolactone (Aldactone) to control her hypertension. Her serum potassium level is 6 mEq/L. For this patient, the nurse's priority would be to assess her:

• A. Neuromuscular function
• B. Bowel sounds
• C. Respiratory rate
• D. Electrocardiogram (ECG) results

Correct answer: D

Rationale: In a patient with a serum potassium level of 6 mEq/L due to spironolactone use, the nurse's priority is to assess the Electrocardiogram (ECG) results. Hyperkalemia can lead to life-threatening arrhythmias, such as ventricular fibrillation, which can be detected on an ECG. While changes in neuromuscular function, bowel sounds, and respiratory rate can occur with hyperkalemia, the most critical assessment related to the patient's condition would be monitoring the ECG for signs of cardiac complications.
