Question 1 of 5
A 26-year-old man with a chronic cough takes codeine for cough suppression. He presents to his primary care physician for follow-up. The patient admits to taking this medication three times daily even when he does not have symptoms. The treating physician must be concerned about which of the following effects?
Correct Answer: A
Rationale: Codeine, an opioid, risks addiction with frequent use. Diarrhea opposes its constipating effect. Euphoria and anxiety are possible but less concerning. Sweating (E) is minor. Addiction potential drives monitoring, given his overuse pattern.
Question 2 of 5
What does it mean when a medication has a half-life?
Correct Answer: B
Rationale: The correct answer is B. When a medication has a half-life, it refers to the time it takes for half of the dose to be eliminated from the bloodstream. Half-life is an important pharmacokinetic parameter which helps determine the dosing interval and duration of action of a drug. By understanding the half-life of a medication, healthcare providers can make informed decisions regarding dosing schedules to maintain therapeutic levels in the body.
Question 3 of 5
Which common adverse effects of selective serotonin reuptake inhibitors (SSRIs) would be stressed by the nurse during patient discharge?
Correct Answer: B
Rationale: SSRIs (e.g., sertraline) commonly cause weight gain and sexual dysfunction (e.g., delayed ejaculation), per patient reports-key for adherence. Drowsiness/coma are overdose risks, not common. Headache/nausea occur but fade. Dry mouth/urine retention are anticholinergic, not SSRI. These impact quality of life, needing emphasis.
Question 4 of 5
When the nurse is administering topical nitroglycerin ointment, which technique is correct?
Correct Answer: D
Rationale: The correct technique when administering topical nitroglycerin ointment is to remove the old ointment before applying new ointment. This is important to prevent an accumulation of the medication on the skin, which can lead to an overdose. It is crucial to follow the prescribed instructions for applying topical medications to ensure safe and effective administration.
Question 5 of 5
A pregnant woman is experiencing hypertension. The nurse knows that which drug is commonly used for a pregnant patient who is experiencing hypertension?
Correct Answer: D
Rationale: Methyldopa is the preferred antihypertensive medication for pregnant women experiencing hypertension. It has been extensively studied and considered safe for both the mother and the fetus. Methyldopa has been shown to effectively lower blood pressure in pregnant women without causing harm to the developing fetus. Other antihypertensive medications, such as Enalapril (Vasote) and Hydrochlorothiazide (HydroDIURIL), are contraindicated during pregnancy as they can cause harm to the fetus. Mannitol (Osmitrol) is an osmotic diuretic primarily used for reducing intracranial pressure or treating cerebral edema, not for hypertension in pregnancy.
Therefore, Methyldopa is the right choice for a pregnant patient with hypertension.
