Nursing Elites

1. Which symptoms should the nurse expect a client to exhibit who is diagnosed with a pheochromocytoma?

• A. Numbness, tingling, and cramps in the extremities.
• B. Headache, diaphoresis, and palpitations.
• C. Cyanosis, fever, and classic signs of shock.
• D. Nausea, vomiting, and muscular weakness.

Correct answer: B

Rationale: Correct. Pheochromocytoma is a catecholamine-secreting non-cancerous tumor of the adrenal medulla. The classic triad of symptoms includes headache, diaphoresis (excessive sweating), and palpitations, which result from the overproduction of catecholamines like epinephrine and norepinephrine. Numbness, tingling, and cramps in the extremities (Option A) are not characteristic of pheochromocytoma. Cyanosis, fever, and classic signs of shock (Option C) are not typical symptoms of this condition. Nausea, vomiting, and muscular weakness (Option D) are not commonly associated with pheochromocytoma.

2. A client is placed on fluid restrictions because of chronic kidney disease (CKD). Which assessment finding would alert the nurse that the client’s fluid balance is stable at this time?

• A. Decreased calcium levels
• B. Increased phosphorus levels
• C. No adventitious sounds in the lungs
• D. Increased edema in the legs

Correct answer: C

Rationale: The absence of adventitious sounds upon auscultation of the lungs is a key indicator that the client's fluid balance is stable. Adventitious sounds, such as crackles or wheezes, are typically heard in conditions of fluid overload, indicating that the body is retaining excess fluid. Choices A and B, decreased calcium levels and increased phosphorus levels, are common laboratory findings associated with chronic kidney disease (CKD) and are not directly related to fluid balance. Increased edema in the legs is a sign of fluid imbalance, suggesting fluid retention in the tissues, which would not indicate stable fluid balance in a client with CKD on fluid restrictions.

3. The nurse is preparing to give trimethoprim-sulfamethoxazole (TMP-SMX) to a patient and notes a petechial rash on the patient’s extremities. The nurse will perform which action?

• A. Hold the dose and notify the provider.
• B. Request an order for a blood glucose level.
• C. Request an order for a BUN and creatinine level.
• D. Request an order for diphenhydramine (Benadryl).

Correct answer: A

Rationale: When a patient on TMP-SMX presents with a petechial rash, it can be indicative of a severe adverse reaction such as thrombocytopenia or a hypersensitivity reaction. The appropriate action for the nurse to take in this situation is to hold the dose of TMP-SMX and notify the healthcare provider immediately. This is crucial to prevent further administration of a medication that may be causing a serious adverse effect. Requesting a blood glucose level (Choice B) is not relevant in this scenario as the patient's presentation is suggestive of a skin-related issue rather than a glucose-related problem. Similarly, requesting a BUN and creatinine level (Choice C) would not address the immediate concern of a petechial rash and its association with TMP-SMX. Requesting an order for diphenhydramine (Choice D) may help manage itching or mild allergic reactions but is not the priority when a petechial rash is observed, as it may indicate a more severe reaction requiring immediate intervention.

4. A nurse obtains a sterile urine specimen from a client’s Foley catheter. After applying a clamp to the drainage tubing distal to the injection port, which action should the nurse take next?

• A. Clamp another section of the tube to create a fixed sample section for retrieval.
• B. Insert a syringe into the injection port and aspirate the quantity of urine required.
• C. Clean the injection port cap of the drainage tubing with a povidone-iodine solution.
• D. Withdraw 10 mL of urine and discard it; then withdraw a fresh sample of urine.

Correct answer: C

Rationale: The correct next action for the nurse to take after applying a clamp to the drainage tubing distal to the injection port is to clean the injection port cap of the catheter drainage tubing with an appropriate antiseptic like povidone-iodine solution or alcohol. This step is crucial to prevent surface contamination before taking the urine sample. Clamping another section of the tube to create a fixed sample section or withdrawing and discarding urine are unnecessary and could lead to potential contamination. Inserting a syringe into the injection port and aspirating the required amount of urine directly from the catheter is the correct method for obtaining the urine sample, but cleaning the injection port cap should precede this step to ensure sterility.

5. A healthcare professional is reviewing the results of renal function testing in a client with renal calculi. Which finding indicates to the healthcare professional that the client’s blood urea nitrogen (BUN) level is within the normal range?

• A. 2 mg/dL
• B. 18 mg/dL
• C. 25 mg/dL
• D. 35 mg/dL

Correct answer: B

Rationale: The normal BUN ranges from 5 to 20 mg/dL. A BUN level of 18 mg/dL falls within this normal range. Values of 25 and 35 mg/dL are elevated, suggesting potential renal insufficiency. Choice A (2 mg/dL) is abnormally low and not indicative of a normal BUN level.
