Nursing Elites

1. In a 29-year-old female client who is being successfully treated for Cushing's syndrome, nurse Lyzette would expect a decline in:

• A. Serum glucose level.
• B. Hair loss.
• C. Bone mineralization.
• D. Menstrual flow.

Correct answer: A

Rationale: The correct answer is A: Serum glucose level. In Cushing's syndrome, there is excess cortisol production which can lead to hyperglycemia. Successful treatment of Cushing's syndrome aims to normalize cortisol levels, resulting in a decline in serum glucose levels. Choice B, hair loss, is not specifically associated with Cushing's syndrome or its treatment. Choice C, bone mineralization, is often compromised in Cushing's syndrome due to the effects of excess cortisol on bones; however, successful treatment would aim to improve bone health rather than decline it. Choice D, menstrual flow, is not directly linked to Cushing's syndrome or its treatment, so a decline in menstrual flow would not be an expected outcome of successful treatment.

2. Why is glucose an important molecule in a cell?

• A. Extraction of energy
• B. Synthesis of protein
• C. Building of genetic material
• D. Formation of cell membranes

Correct answer: A

Rationale: Glucose is a crucial molecule in cells because it serves as the primary source of energy through cellular respiration. Choice B, the synthesis of protein, is incorrect because proteins are typically synthesized from amino acids, not glucose. Choice C, the building of genetic material, is incorrect because genetic material, such as DNA and RNA, is not directly built from glucose. Choice D, the formation of cell membranes, is also incorrect as cell membranes are primarily composed of lipids and proteins, not glucose.

3. A nurse is assigned to care for a group of clients. On review of the clients' medical records, the nurse determines that which client is at risk for excess fluid volume?

• A. The client taking diuretics
• B. The client with renal failure
• C. The client with an ileostomy
• D. The client who requires gastrointestinal suctioning

Correct answer: B

Rationale: The correct answer is B. Clients with renal failure are unable to excrete fluids effectively, leading to an increased risk of fluid volume excess. Option A, the client taking diuretics, would be at risk for fluid volume deficit due to increased urine output caused by the diuretics. Option C, the client with an ileostomy, is at risk for fluid volume deficit due to increased output from the ileostomy. Option D, the client who requires gastrointestinal suctioning, may be at risk for dehydration, but not specifically excess fluid volume.

4. A healthcare professional reviews a client's electrolyte laboratory report and notes that the potassium level is 3.2 mEq/L. Which of the following would the healthcare professional note on the electrocardiogram as a result of the laboratory value?

• A. U waves
• B. Absent P waves
• C. Elevated T waves
• D. Elevated ST segment

Correct answer: A

Rationale: The correct answer is A: U waves. A low potassium level (hypokalemia) can manifest as U waves on an ECG. U waves are small, extra deflections seen after the T wave and may indicate cardiac irritability. Absent P waves (Choice B) are associated with conditions like atrial fibrillation. Elevated T waves (Choice C) can be seen in hyperkalemia, not hypokalemia. Elevated ST segment (Choice D) is not typically associated with low potassium levels but can be seen in conditions like myocardial infarction.

5. A client with diabetes mellitus visits a health care clinic. The client's diabetes was previously well controlled with glyburide (Diabeta), 5 mg PO daily, but recently the fasting blood glucose has been running 180-200 mg/dl. Which medication, if added to the client's regimen, may have contributed to the hyperglycemia?

• A. Prednisone (Deltasone)
• B. Atenolol (Tenormin)
• C. Phenelzine (Nardil)
• D. Allopurinol (Zyloprim)

Correct answer: A

Rationale: Prednisone, a corticosteroid, can increase blood glucose levels by promoting gluconeogenesis and decreasing glucose uptake by cells. This medication can lead to hyperglycemia in patients, especially those with diabetes mellitus. Atenolol (Tenormin) is a beta-blocker and is not known to significantly affect blood glucose levels. Phenelzine (Nardil) is a monoamine oxidase inhibitor used to treat depression and anxiety disorders; it does not typically impact blood glucose levels. Allopurinol (Zyloprim) is a xanthine oxidase inhibitor used to manage gout and does not interfere with blood glucose regulation.
