1. Twenty-four hours after starting to take oral penicillin for strep throat, a client calls the nurse to report the onset of a rash on the chest. What action should the nurse implement?
- A. Instruct the client to discontinue the penicillin immediately
- B. Instruct the client regarding the use of topical analgesic cream PRN
- C. Question the client about any other related symptoms
- D. Reinforce the need to take all doses of the penicillin
Correct answer: A
Rationale: In this scenario, the client has developed a rash after starting oral penicillin, which can indicate an allergic reaction. It is crucial for the nurse to instruct the client to discontinue the penicillin immediately. Continuing the medication can potentially lead to severe allergic reactions. Instructing about topical analgesic cream or questioning about other related symptoms may delay appropriate action in case of a severe allergic reaction. Reinforcing the need to complete all doses is not appropriate when an allergic reaction is suspected, as safety takes precedence over completing the antibiotic course.
2. A client has been prescribed losartan. Which change in data indicates to the practical nurse (PN) that the desired effect of this medication has been achieved?
- A. Dependent edema reduced from +3 to +1.
- B. Serum HDL increased from 35 to 55 mg/dL.
- C. Pulse rate reduced from 150 to 90 beats/min.
- D. Blood pressure reduced from 160/90 to 130/80 mm Hg.
Correct answer: D
Rationale: The correct answer is D. Losartan is prescribed for the treatment of hypertension. The desired effect of losartan is to reduce blood pressure. Therefore, a reduction in blood pressure from 160/90 to 130/80 mm Hg indicates that the desired effect of the medication has been achieved. Choices A, B, and C are not specific effects of losartan and do not directly relate to the expected outcomes of this medication. Dependent edema, serum HDL levels, and pulse rate are not typically influenced by losartan, making choices A, B, and C incorrect.
3. A client with asthma is prescribed fluticasone. The nurse should instruct the client to use this medication at which time?
- A. During an asthma attack
- B. Twice a day
- C. Once a day
- D. At night before bed
Correct answer: C
Rationale: Fluticasone is a maintenance medication for asthma aimed at controlling symptoms. It should be taken once a day on a regular basis to provide ongoing relief and prevent asthma symptoms, rather than being used to treat acute asthma attacks. Therefore, the correct answer is to use it once a day. Choices A, B, and D are incorrect because using fluticasone during an asthma attack, twice a day, or only at night before bed does not align with the medication's purpose of being a daily maintenance therapy.
4. 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.
5. A client with a history of heart failure is prescribed carvedilol. The nurse should monitor the client for which adverse effect?
- A. Dizziness upon standing
- B. Weight loss
- C. Bradycardia
- D. Hypotension
Correct answer: D
Rationale: The correct answer is D: Hypotension. Carvedilol, a beta-blocker, can lead to hypotension by blocking the effects of adrenaline, which can cause blood vessels to dilate and reduce blood pressure. While dizziness upon standing is a potential adverse effect of carvedilol, it is more specifically related to orthostatic hypotension, which is a form of hypotension that occurs when a person stands up from a sitting or lying position. Weight loss and bradycardia are not typically associated with carvedilol use. Therefore, the nurse should primarily monitor for hypotension in a client taking carvedilol.
