Nursing Elites

1. 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.

2. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which laboratory value is most concerning?

• A. Serum sodium of 135 mEq/L
• B. Serum potassium of 4.0 mEq/L
• C. Serum bicarbonate of 18 mEq/L
• D. Serum glucose of 300 mg/dL

Correct answer: C

Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with COPD as it indicates metabolic acidosis, requiring immediate intervention. In COPD, patients often retain carbon dioxide, leading to respiratory acidosis. A low serum bicarbonate level suggests that the body is compensating for this respiratory acidosis by increasing bicarbonate levels to maintain balance. Therefore, a low serum bicarbonate level in this scenario is alarming. Choices A, B, and D are within normal ranges and not directly related to the acid-base imbalance seen in COPD.

3. The nurse notes that a client has been receiving hydromorphone (Dilaudid) every six hours for four days. What assessment is most important for the nurse to complete?

• A. Auscultate the client's bowel sounds
• B. Observe for edema around the ankles
• C. Measure the client's capillary glucose level
• D. Count the apical and radial pulses simultaneously

Correct answer: A

Rationale: The correct answer is to auscultate the client's bowel sounds. Hydromorphone is a potent opioid analgesic that can slow peristalsis and commonly cause constipation. By assessing the client's bowel sounds, the nurse can monitor for any signs of decreased bowel motility or potential constipation. Observing for edema (Choice B) is not directly related to hydromorphone administration. Measuring capillary glucose levels (Choice C) is not the priority in this situation. Counting the apical and radial pulses simultaneously (Choice D) is not specifically indicated in this scenario involving hydromorphone administration.

4. In assessing a client 48 hours following a fracture, the nurse observes ecchymosis at the fracture site and recognizes that hematoma formation at the bone fragment site has occurred. What action should the nurse implement?

• A. Document the extent of the bruising in the medical record.
• B. Apply a cold compress to the area.
• C. Elevate the affected limb.
• D. Notify the healthcare provider.

Correct answer: A

Rationale: After observing ecchymosis at the fracture site, indicating hematoma formation, the nurse's priority is to document the extent of the bruising in the medical record. This documentation helps track the client's condition, aids in treatment planning, and serves as a baseline for monitoring changes. Applying a cold compress (choice B) may be contraindicated due to the risk of vasoconstriction and potential tissue damage. Elevating the affected limb (choice C) can be beneficial for reducing swelling in some cases, but documenting the bruising is the immediate concern. Notifying the healthcare provider (choice D) is not necessary at this stage unless there are other concerning symptoms or complications beyond the hematoma formation.

5. A client with a history of chronic heart failure is admitted with shortness of breath. Which laboratory value should be closely monitored?

• A. Serum sodium level
• B. Serum potassium level
• C. Serum creatinine level
• D. Hemoglobin level

Correct answer: B

Rationale: Corrected Rationale: In a client with chronic heart failure, serum potassium levels should be closely monitored to assess for hyperkalemia, which can worsen heart failure. Monitoring serum sodium levels is not the priority in this case. Serum creatinine level monitoring is more related to kidney function than heart failure. Hemoglobin levels are important but not the primary concern when assessing heart failure exacerbation.
