Question 1 of 5
The nurse is caring for a 55-year-old patient receiving metoprolol (Lopressor). What statement by the patient would lead the nurse to believe that he needs additional instruction?
Correct Answer: B
Rationale: OTC medications can interact to increase or decrease the effects of antiadrenergic drugs. Antacids decrease the effects of beta-adrenergic blocking drugs. Decreased antihypertensive effects result when taken with ibuprofen. Other options reflect correct statements and would not indicate that the patient would need further instruction. The nurse should educate the patient about potential drug interactions and the importance of consulting their healthcare provider before taking OTC medications.
Question 2 of 5
The drug that will most likely be used for treatment of erectile dysfunction (ED) is
Correct Answer: D
Rationale: Sildenafil (Viagra), a phosphodiesterase-5 inhibitor, treats erectile dysfunction (ED) by enhancing penile blood flow, a first-line therapy. Leuprolide suppresses testosterone for prostate cancer, worsening ED. Finasteride and tamsulosin, for BPH, don't target ED and may cause it. Sildenafil's vascular action offers rapid efficacy, making it the go-to choice.
Question 3 of 5
What is the unlabeled use for
Correct Answer: A
Rationale: The unlabeled use for a medication refers to a use that is not approved by regulatory agencies but has shown effectiveness in clinical practice. In this case, the unlabeled use for a medication might be to treat PTSD (Post-Traumatic Stress Disorder). While the medication may not be specifically indicated for this condition, it may have shown benefits in managing the symptoms of PTSD based on clinical experience or research studies. It is important to note that using a medication for an unlabeled use should always be done under the supervision of a healthcare professional.
Question 4 of 5
While on pentamidine (Pentam) infusion therapy. The nurse must anticipate doing which of the following?
Correct Answer: B
Rationale: Pentamidine (Pentam) is a medication used for the treatment and prevention of Pneumocystis carinii pneumonia (PCP) in immunocompromised patients, such as those with HIV/AIDS. A known side effect of pentamidine therapy is ocular toxicity, including retinal damage. The nurse must closely monitor the client for signs and symptoms of retinal toxicity, such as changes in vision, eye pain, or sensitivity to light. Regular ophthalmologic evaluations may also be necessary to detect any ocular complications early and prevent permanent damage. Hence, observing for signs of retinal damage is crucial while the client is on pentamidine infusion therapy.
Question 5 of 5
When monitoring a patient who is taking hydrochlorothiazide (HydroDIURIL), the nurse notes that which drug is most likely to cause a severe interaction with the diuretic?
Correct Answer: A
Rationale: Hydrochlorothiazide (HydroDIURIL) is a diuretic that can cause electrolyte imbalances, particularly hypokalemia (low potassium levels). Digitalis (digoxin) is a medication commonly used to treat heart conditions, and its therapeutic effect is dependent on adequate potassium levels. If a patient taking hydrochlorothiazide becomes hypokalemic and then takes digitalis, it can lead to an increased risk of digitalis toxicity. This severe interaction highlights the importance of monitoring potassium levels and potential drug interactions when patients are taking hydrochlorothiazide. Potassium supplements would help counteract the potassium loss caused by hydrochlorothiazide and minimize the risk of interactions with digitalis.
