Nursing Elites

1. The client has been vomiting and has had numerous episodes of diarrhea. Which laboratory test should the nurse monitor?

• A. Serum calcium.
• B. Serum phosphorus.
• C. Serum potassium.
• D. Serum sodium.

Correct answer: C

Rationale: During episodes of vomiting and diarrhea, there is a risk of significant potassium loss, leading to potential electrolyte imbalances. Monitoring serum potassium levels is crucial in this situation to assess and manage any abnormalities promptly. Serum calcium (Choice A) is not typically affected by vomiting and diarrhea. Serum phosphorus (Choice B) levels are not commonly altered by these symptoms. Serum sodium (Choice D) may be affected in severe cases of dehydration, but potassium monitoring is a higher priority due to its potential for rapid depletion in vomiting and diarrhea.

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. The healthcare provider is monitoring a client with Cushing's syndrome. Which of the following findings should be reported to the healthcare provider immediately?

• A. Hyperglycemia
• B. Hypertension
• C. Low-grade fever
• D. Weight gain

Correct answer: C

Rationale: In a client with Cushing's syndrome, a low-grade fever should be reported immediately as it may indicate an infection. Clients with Cushing's syndrome are immunosuppressed, making them more susceptible to infections. Hyperglycemia and hypertension are common findings in Cushing's syndrome and are managed as part of the condition. Weight gain is also a common symptom in Cushing's syndrome and may not require immediate reporting unless it is sudden and severe.

4. A female client with physical findings suggestive of a hyperpituitary condition undergoes an extensive diagnostic workup. Test results reveal a pituitary tumor, necessitating a transsphenoidal hypophysectomy. The evening before the surgery, Nurse Jacob reviews preoperative and postoperative instructions provided to the client earlier. Which postoperative instruction should the nurse emphasize?

• A. You must lie flat for 24 hours after surgery.
• B. You must avoid coughing, sneezing, and blowing your nose.
• C. You must restrict your fluid intake.
• D. You must report ringing in your ears immediately.

Correct answer: B

Rationale: Following a transsphenoidal hypophysectomy, it is crucial to avoid activities such as coughing, sneezing, and blowing the nose to prevent an increase in intracranial pressure or the risk of cerebrospinal fluid leakage. Coughing, sneezing, or nose blowing can strain the surgical site, potentially leading to complications. Lying flat for 24 hours is not typically required after this surgery. Fluid intake should be encouraged to prevent dehydration. Ringing in the ears is not a common complication associated with this type of surgery.

5. Which of these signs suggests that a male client with the syndrome of inappropriate antidiuretic hormone (SIADH) secretion is experiencing complications?

• A. Tetanic contractions
• B. Neck vein distention
• C. Weight loss
• D. Polyuria

Correct answer: B

Rationale: Neck vein distention is a sign of fluid overload, a complication of SIADH due to water retention. Tetanic contractions (Choice A) are not typically associated with SIADH. Weight loss (Choice C) is not a common complication of SIADH, as patients often experience fluid retention and weight gain. Polyuria (Choice D) is also not a typical sign of SIADH, as the condition is characterized by water retention and decreased urine output.
