1. The practical nurse administers lactulose to a client. Which client outcome would indicate a therapeutic response?
- A. An increase in urine output
- B. Two to three soft stools per day
- C. Absence of nausea
- D. Decreased serum potassium
Correct answer: B
Rationale: Lactulose is a type of laxative that works by preventing the absorption of ammonia in the colon, leading to increased water absorption in the stool and softening of the stool. The therapeutic response to lactulose is indicated by the passage of two to three soft stools per day, showing that the medication is effectively promoting bowel movements.
2. A client is taking levodopa-carbidopa for Parkinson's disease. The nurse should include which instruction when educating the client about this medication?
- A. Increase fluid intake to prevent dehydration.
- B. Take medication with food to improve absorption.
- C. Take medication at bedtime to avoid daytime drowsiness.
- D. It can cause nausea and dizziness.
Correct answer: A
Rationale: The correct instruction for a client taking levodopa-carbidopa for Parkinson's disease is to increase fluid intake to prevent dehydration. Levodopa-carbidopa should be taken with food to reduce gastrointestinal upset and improve absorption. Taking medication at bedtime is not necessary to avoid daytime drowsiness. It is crucial to prevent dehydration due to the medication's side effects. Choice B is incorrect because the medication should be taken with food, not at bedtime. Choice C is incorrect as taking the medication with food, rather than on an empty stomach, aids in absorption and reduces gastrointestinal side effects. Choice D is incorrect as it states the side effects of the medication rather than providing specific instructions on its administration.
3. A client with a diagnosis of schizophrenia is prescribed lurasidone. The nurse should monitor the client for which potential side effect?
- A. Weight gain
- B. Dry mouth
- C. Nausea
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Weight gain. When a client is prescribed lurasidone, monitoring for weight gain is essential as lurasidone can cause this side effect. Patients on lurasidone should have their weight monitored regularly to detect any changes that may occur. Options B, C, and D are not typically associated with lurasidone use, making them less likely to be a direct side effect of this medication.
4. A client is prescribed nitroglycerin sublingual tablets. The practical nurse should reinforce which instruction?
- A. Store the tablets in a cool, dry place.
- B. Take one tablet every 5 minutes until pain is relieved, up to three tablets.
- C. Swallow the tablets whole.
- D. Chew the tablets for faster relief.
Correct answer: A
Rationale: Nitroglycerin sublingual tablets are sensitive to heat and moisture, so they should be stored in a cool, dry place to maintain their efficacy. Storing them in a cool, dry place helps prevent degradation of the medication. Choice B is incorrect because nitroglycerin tablets should be taken as directed by the healthcare provider to avoid potential overdose or adverse effects. Choice C is incorrect because sublingual tablets should be placed under the tongue to dissolve and be absorbed, not swallowed, to ensure their quick action. Choice D is incorrect because sublingual tablets should not be chewed; they are meant to be absorbed through the tissues under the tongue, and chewing them may alter their effectiveness.
5. A client is receiving heparin to treat a deep vein thrombosis. The nurse should monitor which laboratory result to assist in evaluating the efficacy of the drug?
- A. Platelet count
- B. Prothrombin time
- C. Partial thromboplastin time
- D. Serum levels of protamine sulfate
Correct answer: C
Rationale: The nurse should monitor the partial thromboplastin time to evaluate the efficacy of heparin. Partial thromboplastin time reflects the anticoagulant effect of heparin by measuring the intrinsic pathway of coagulation. Platelet count assesses platelet levels and is not specific to heparin efficacy. Prothrombin time is used to monitor warfarin therapy. Serum levels of protamine sulfate are not used to evaluate the efficacy of heparin.
