Nursing Elites

1. An elderly client reports new-onset confusion, nausea, dysuria, and urgency. What action should the nurse take first?

• A. Initiate intravenous fluids
• B. Obtain a clean-catch midstream urine specimen
• C. Administer antibiotics
• D. Start a Foley catheter to obtain a sterile sample

Correct answer: B

Rationale: The correct first action for the nurse to take in this scenario is to obtain a clean-catch midstream urine specimen. The client's symptoms of confusion, nausea, dysuria, and urgency are suggestive of a urinary tract infection (UTI). To confirm the diagnosis and identify the causative organism, a urine specimen should be collected before initiating any treatment. Initiating intravenous fluids (Choice A) may be necessary later based on the client's condition but is not the initial priority. Administering antibiotics (Choice C) should be done after confirming the diagnosis through urine culture. Starting a Foley catheter (Choice D) to obtain a sterile sample is more invasive and should not be the first step in the assessment and management of a suspected UTI.

2. A client with diabetic ketoacidosis (DKA) is receiving an insulin infusion. Which finding indicates that the treatment is effective?

• A. Potassium level of 4.0 mEq/L.
• B. Blood glucose level of 180 mg/dL.
• C. Urine output of 50 mL/hour.
• D. Absence of ketones in the urine.

Correct answer: D

Rationale: The correct answer is D: Absence of ketones in the urine. In a client with diabetic ketoacidosis (DKA) receiving an insulin infusion, the absence of ketones in the urine indicates that ketoacidosis is resolving. This is a crucial finding as it shows that the insulin therapy is effectively addressing the metabolic imbalance causing DKA. Choices A, B, and C are incorrect: A potassium level of 4.0 mEq/L is within normal range but does not directly reflect the resolution of DKA; a blood glucose level of 180 mg/dL, while improved, is still high and does not specifically indicate the resolution of ketoacidosis; urine output of 50 mL/hour is within normal limits but does not directly point to the resolution of DKA.

3. A client is admitted to isolation with active tuberculosis. What infection control measures should the nurse implement?

• A. Initiate protective environment precautions.
• B. Use droplet precautions only.
• C. Ensure a positive pressure environment in the room.
• D. Implement negative pressure and contact precautions.

Correct answer: D

Rationale: When caring for a client with active tuberculosis, it is crucial to implement negative pressure rooms and contact precautions to prevent the spread of infection. Choice A, initiating protective environment precautions, is incorrect as this is not the recommended approach for tuberculosis. Choice B, using droplet precautions only, is insufficient as tuberculosis requires additional precautions. Choice C, ensuring a positive pressure environment in the room, is incorrect because negative pressure rooms are necessary to contain airborne pathogens like tuberculosis. Therefore, the most appropriate measures include implementing negative pressure rooms and contact precautions.

4. An S3 heart sound is auscultated in a client in her third trimester of pregnancy. What intervention should the nurse take?

• A. Perform a 12-lead electrocardiogram
• B. Document in the client's record
• C. Notify the healthcare provider immediately
• D. Assess for signs of heart failure

Correct answer: B

Rationale: An S3 heart sound is often a normal finding in pregnant women due to increased blood volume and cardiac output. The nurse should document the finding as part of the routine assessment unless accompanied by other abnormal symptoms. Performing a 12-lead electrocardiogram (Choice A) is unnecessary for a normal S3 heart sound in pregnancy. Notifying the healthcare provider immediately (Choice C) is premature and may lead to unnecessary interventions. Assessing for signs of heart failure (Choice D) is not indicated as an isolated S3 heart sound is typically benign in pregnancy.

5. A client with liver cirrhosis is receiving lactulose for hepatic encephalopathy. Which finding indicates the medication is effective?

• A. The client's level of consciousness improves.
• B. The client's ammonia level decreases.
• C. The client has three bowel movements daily.
• D. The client's liver enzymes return to normal.

Correct answer: B

Rationale: The correct answer is B: "The client's ammonia level decreases." In hepatic encephalopathy, elevated ammonia levels contribute to neurological symptoms. Lactulose works by promoting the excretion of ammonia in the stool, leading to decreased serum ammonia levels. Therefore, a decrease in ammonia levels indicates that lactulose is effectively reducing ammonia buildup, improving hepatic encephalopathy symptoms. Choices A, C, and D are incorrect because improvement in level of consciousness, bowel movements, or normalization of liver enzymes may not directly reflect the effectiveness of lactulose in reducing ammonia levels and improving hepatic encephalopathy.
