1. A patient with atrial fibrillation is prescribed warfarin. Which laboratory test should the nurse monitor to assess the effectiveness of the medication?

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT)/INR. Warfarin affects the clotting ability of the blood by inhibiting vitamin K-dependent clotting factors. Monitoring the prothrombin time (PT) and international normalized ratio (INR) is crucial to assess the effectiveness and safety of warfarin therapy. These tests help determine if the patient is within the desired anticoagulation range to prevent either clotting issues or excessive bleeding.

2. The healthcare provider in the outpatient clinic has obtained health histories for these new patients. Which patient may need referral for genetic testing?

Correct answer: C

Rationale: The 34-year-old patient who has a sibling with newly diagnosed polycystic kidney disease may need referral for genetic testing. Polycystic kidney disease is an autosomal dominant disorder that can be asymptomatic until later in life. Presymptomatic testing can provide valuable information for guiding lifestyle and family planning decisions. The other patients do not present indications for genetic testing based on the information provided in their health histories. The 35-year-old patient's maternal grandparents' strokes are not indicative of a need for genetic testing. The 18-year-old patient's child having cerebral palsy is not a direct indication for genetic testing of the patient herself. The 50-year-old patient's symptoms are more likely related to smoking and respiratory issues, not genetic predisposition to a specific disease.

3. While assessing a client with preeclampsia who is receiving magnesium sulfate, the nurse notes her deep tendon reflexes are 1+, respiratory rate is 12 breaths/minute, urinary output is 90 ml in 4 hours, and magnesium sulfate level is 9 mg/dl. What intervention should the nurse implement based on these findings?

Correct answer: C

Rationale: The nurse should stop the magnesium sulfate infusion immediately in a client with preeclampsia exhibiting diminished reflexes, respiratory depression, and low urinary output, which indicate magnesium sulfate toxicity. This action is crucial to prevent further complications and adverse effects on the client.

4. The client with gastroesophageal reflux disease (GERD) is being taught about dietary modifications by the nurse. Which instruction should the nurse include?

Correct answer: B

Rationale: Avoiding lying down immediately after eating is essential in managing GERD as it helps prevent reflux symptoms by allowing gravity to assist in keeping stomach contents down. Lying down can worsen symptoms by allowing acid to flow back into the esophagus.

5. A patient with hyperlipidemia is prescribed atorvastatin. What lab test should be monitored periodically to assess for adverse effects?

Correct answer: A

Rationale: The correct answer is A: Liver function tests. Patients on atorvastatin should have their liver function tests monitored periodically to detect any potential liver damage. Atorvastatin, a statin medication used to lower cholesterol levels, can rarely cause liver enzyme abnormalities, so regular monitoring is essential to identify any adverse effects early on. Monitoring the complete blood count (choice B), blood glucose levels (choice C), or serum potassium (choice D) is not typically required specifically for atorvastatin therapy. While these tests may be important for other conditions or medications, liver function tests are the most relevant for monitoring the adverse effects of atorvastatin.
