Nursing Elites

1. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be monitored closely?

• A. Serum potassium
• B. Hemoglobin
• C. Serum sodium
• D. White blood cell count

Correct answer: A

Rationale: The correct answer is A: Serum potassium. When a client with chronic kidney disease is undergoing erythropoietin therapy, monitoring serum potassium levels is crucial. Erythropoietin can stimulate red blood cell production, which may lead to an increase in potassium levels, predisposing the client to hyperkalemia. Monitoring serum potassium levels helps in early detection of hyperkalemia and appropriate intervention. Choices B, C, and D are incorrect because although hemoglobin, serum sodium, and white blood cell count are important parameters to monitor in various clinical conditions, they are not specifically associated with erythropoietin therapy in chronic kidney disease.

2. The nurse is reviewing a client's electrocardiogram and determines the PR interval (PRI) is prolonged. What does this finding indicate?

• A. Initiation of the impulses from a location outside the SA node
• B. Inability of the SA node to initiate an impulse at the normal rate
• C. Increased conduction time from the SA node to the AV junction
• D. Interference with the conduction through one or both ventricles

Correct answer: C

Rationale: When the PR interval is prolonged, it signifies an increased conduction time from the SA node through the AV junction. This finding is characteristic of a first-degree heart block where there is a delay in the electrical conduction at the level of the AV node. Choices A, B, and D are incorrect as they do not accurately reflect the significance of a prolonged PR interval.

3. A client with a history of chronic kidney disease (CKD) is scheduled for a CT scan with contrast. Which laboratory value should the nurse review before the procedure?

• A. Serum creatinine
• B. Blood urea nitrogen (BUN)
• C. Serum potassium
• D. Serum glucose

Correct answer: A

Rationale: The correct answer is A: Serum creatinine. Before a CT scan with contrast, the nurse should review the serum creatinine level. This is crucial in patients with CKD because contrast agents can potentially worsen kidney function and lead to contrast-induced nephropathy. Monitoring serum creatinine helps assess kidney function and determine the risk of complications. Choices B, C, and D are less relevant in this scenario. Blood urea nitrogen (BUN) is another marker of kidney function, but serum creatinine is a more specific indicator. Serum potassium levels are important in assessing electrolyte balance but are not directly related to the risk of contrast-induced nephropathy. Serum glucose levels are not typically a primary concern before a CT scan with contrast in a patient with CKD.

4. The healthcare provider prescribes atenolol 50 mg daily for a client with angina pectoris. Which finding should the nurse report to the healthcare provider before administering this medication?

• A. Irregular pulse.
• B. Tachycardia.
• C. Chest pain.
• D. Urinary frequency.

Correct answer: A

Rationale: The correct answer is A: Irregular pulse. An irregular pulse may indicate an arrhythmia, which could be exacerbated by atenolol, a beta-blocker used to treat angina pectoris. Atenolol works by slowing the heart rate, so if the patient already has an irregular pulse, it could worsen with the medication. Tachycardia (choice B) would actually be an expected finding in a patient with angina pectoris, and atenolol is used to help reduce the heart rate in such cases. Chest pain (choice C) is a symptom that atenolol is meant to alleviate, so it would not be a reason to withhold the medication. Urinary frequency (choice D) is not directly related to the administration of atenolol for angina pectoris and would not require immediate reporting to the healthcare provider.

5. A male client is having abdominal pain after a left femoral angioplasty and stent, and is asking for additional pain medication for right lower quadrant pain (9/10). Two hours ago, he received hydrocodone/acetaminophen 7.5/7.50 mg. His vital signs are elevated from the previous hour: temperature 97.8 F, heart rate 102 beats per minute, respiration 20 breaths per minute. His abdomen is swollen, the groin access site is tender, peripheral pulses are present, but the left leg is larger than the right. Preoperatively, clopidogrel was prescribed for a history of previous peripheral stents. Another nurse is holding manual pressure on the femoral arterial access site which may be leaking into the abdomen. What data is needed to make this report complete?

• A. Client's lungs are clear bilaterally, and oxygen saturation is 97%.
• B. The surgeon needs to see the client immediately to evaluate the situation.
• C. Left peripheral pulses were present only by Doppler pre-procedure.
• D. Client's history includes multiple back surgeries and chronic pain.

Correct answer: B

Rationale: The correct answer is B. Immediate evaluation by the surgeon is necessary due to the possibility of an internal hemorrhage, which is a life-threatening condition. Choice A is incorrect as lung status and oxygen saturation are not the priority in this situation. Choice C is not relevant to the current urgent issue. Choice D, while providing additional history, is not pertinent to the immediate concern of a potential internal hemorrhage post angioplasty and stent placement.
