Question 1 of 5
A healthcare professional in a provider's clinic is caring for a client who reports erectile dysfunction and requests a prescription for sildenafil. Which of the following medications currently prescribed for the client is a contraindication to taking sildenafil?
Correct Answer: A
Rationale: Sildenafil is contraindicated with nitrates like isosorbide due to the risk of severe hypotension. Isosorbide is a nitrate that can potentiate the hypotensive effects of sildenafil, leading to a dangerous drop in blood pressure. Therefore, it is essential to avoid concurrent use of isosorbide and sildenafil to prevent adverse effects. Phenytoin, metronidazole, and prednisone do not have significant interactions with sildenafil and are not contraindicated when used together.
Question 2 of 5
While caring for a client receiving IV heparin, which of the following findings should the nurse identify as an adverse effect of this medication?
Correct Answer: C
Rationale: Thrombocytopenia, a decrease in platelet count, is a known adverse effect associated with heparin therapy. It can lead to an increased risk of bleeding and should be closely monitored during treatment. Choices A, B, and D are incorrect. Hypertension is not typically associated with heparin use; hyperglycemia is not a common adverse effect of heparin; leukopenia is not a primary side effect of heparin therapy.
Question 3 of 5
A client is receiving warfarin therapy. Which of the following findings should the nurse identify as an adverse effect of warfarin?
Correct Answer: B
Rationale: Epistaxis, or nosebleeds, can be an indication of excessive anticoagulation while on warfarin therapy. Warfarin is a blood thinner that helps prevent blood clots. Epistaxis can occur as a result of the blood-thinning effects of warfarin, leading to increased bleeding tendencies, including nosebleeds. Nausea, diarrhea, and dyspepsia are not typically associated with warfarin therapy; therefore, they are not the adverse effects the nurse should identify in a client receiving warfarin.
Question 4 of 5
When teaching a client with a new prescription for warfarin, which statement should the nurse include?
Correct Answer: C
Rationale: The correct statement the nurse should include when teaching a client with a new prescription for warfarin is to report any signs of bleeding to their provider. Bleeding can indicate excessive anticoagulation, a potential side effect of warfarin therapy that needs prompt medical attention. Choices A, B, and D are incorrect because while oral hygiene measures, dietary considerations, and skin care are important, they are not the priority when teaching a client about warfarin therapy. Monitoring for and reporting signs of bleeding is crucial due to the anticoagulant effects of warfarin.
Question 5 of 5
A client has a new prescription for lisinopril. Which of the following findings should the nurse monitor as an adverse effect of this medication?
Correct Answer: A
Rationale: A common adverse effect of lisinopril is a persistent dry cough. Lisinopril is an ACE inhibitor that can cause irritation in the respiratory tract, leading to a cough. Monitoring for a persistent cough is essential as it may indicate a serious adverse effect that requires medical attention. Hyperglycemia (Choice B) is not a common adverse effect of lisinopril. Headache (Choice C) and dry mouth (Choice D) are not typically associated with lisinopril use. Therefore, the correct answer is A: Cough.
