1. A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which assessment finding is most concerning?
- A. Bradycardia
- B. Muscle weakness
- C. Peaked T waves on the ECG
- D. Decreased deep tendon reflexes
Correct answer: C
Rationale: The correct answer is C: Peaked T waves on the ECG. In hyperkalemia, elevated potassium levels can affect the heart's electrical activity, leading to changes on the ECG such as peaked T waves. This finding is concerning as it can progress to serious cardiac arrhythmias, including ventricular tachycardia and fibrillation. Bradycardia (choice A) and decreased deep tendon reflexes (choice D) are not typically associated with hyperkalemia. While muscle weakness (choice B) can occur in hyperkalemia due to its effect on neuromuscular function, the most concerning assessment finding indicating the need for immediate intervention in this scenario is peaked T waves on the ECG.
2. An elderly client seems confused and reports the onset of nausea, dysuria, and urgency with incontinence. Which action should the nurse implement?
- A. Auscultate for renal bruits
- B. Obtain a clean catch mid-stream specimen
- C. Use a dipstick to measure for urinary ketones
- D. Begin to strain the client's urine
Correct answer: B
Rationale: This elderly client is presenting symptoms consistent with a urinary tract infection (UTI), such as confusion, nausea, dysuria, urgency, and incontinence. The best course of action for the nurse is to obtain a clean catch mid-stream specimen. This specimen will help identify the causative agent of the UTI, allowing for targeted treatment with an appropriate anti-infective agent. Auscultating for renal bruits (Choice A) is not indicated in this scenario as the client's symptoms point towards a UTI rather than a renal issue. Using a dipstick to measure for urinary ketones (Choice C) is not relevant in the context of UTI symptoms. Beginning to strain the client's urine (Choice D) would not address the need to identify the causative agent for targeted treatment.
3. An elderly female client with osteoarthritis reports increasing pain and stiffness in her right knee and asks how to reduce these symptoms. In responding to the client, the nurse recognizes what pathology as the cause of her symptoms?
- A. Destruction of joint cartilage.
- B. Inflammation of synovial membrane.
- C. Formation of bone spurs.
- D. Reduction of joint space.
Correct answer: A
Rationale: Corrected Rationale: Osteoarthritis typically involves the destruction of joint cartilage, leading to pain and stiffness. This destruction of joint cartilage results in bone rubbing against bone, causing pain and reduced mobility. Choices B, C, and D are incorrect. Inflammation of the synovial membrane (choice B) is more commonly associated with rheumatoid arthritis. Formation of bone spurs (choice C) and reduction of joint space (choice D) are manifestations that can occur as a result of osteoarthritis but are not the primary pathology responsible for the symptoms of pain and stiffness.
4. The nurse is assessing a client with left-sided heart failure. Which clinical finding requires immediate intervention?
- A. Jugular venous distention
- B. Shortness of breath
- C. Crackles in the lungs
- D. Peripheral edema
Correct answer: C
Rationale: Corrected Rationale: In a client with left-sided heart failure, crackles in the lungs are the most concerning finding as they indicate pulmonary congestion, which requires immediate intervention to prevent worsening heart failure symptoms and respiratory distress. Jugular venous distention, shortness of breath, and peripheral edema are also common in heart failure but are not as critical as crackles in the lungs because they may indicate fluid overload or right-sided heart failure, which are important to address but not as urgently as managing pulmonary congestion.
5. A client with a history of chronic kidney disease is scheduled for a CT scan with contrast. Which laboratory value should the nurse review before the procedure?
- A. Serum potassium
- B. Blood urea nitrogen (BUN)
- C. Serum creatinine
- D. Serum glucose
Correct answer: C
Rationale: Before a CT scan with contrast, the nurse should review the serum creatinine level. This is crucial in assessing kidney function because contrast agents can potentially worsen renal function, leading to contrast-induced nephropathy. Monitoring serum creatinine helps in identifying patients at risk and taking necessary precautions. Serum potassium (Choice A) is important in conditions like hyperkalemia but is not the priority before a contrast CT scan. Blood urea nitrogen (BUN) (Choice B) is another renal function test but is not as specific as serum creatinine for assessing kidney function. Serum glucose (Choice D) is important in monitoring blood sugar levels, especially in diabetic patients, but it is not directly related to the risk of contrast-induced nephropathy in this scenario.
