Question 1 of 5
After administering the drug Atropine to a patient, the nurse notices side effects of dry mouth, tachycardia, and drowsiness. The nurse suspects ans overdose of the drug. Which of the following is the antidote for Atropine?
Correct Answer: C
Rationale: Physostigmine is the antidote for Atropine overdose. Atropine is an anticholinergic drug that blocks the action of acetylcholine. Physostigmine works by increasing the levels of acetylcholine in the body, counteracting the effects of Atropine. It can help reverse the side effects of Atropine overdose, such as dry mouth, tachycardia, and drowsiness. Flumazenil is the antidote for benzodiazepines, Naloxone is the antidote for opioids, and Protamine sulfate is the antidote for heparin.
Question 2 of 5
Which of the following does not describe intravenous injection.
Correct Answer: D
Rationale: The statement "Convenient, safe, economical" does not accurately describe intravenous injection. Intravenous injection is generally considered to be less convenient compared to other routes of administration due to the need for proper training, sterile technique, and close monitoring during drug administration. While it can be effective in delivering drugs quickly and directly into the bloodstream, it is not always the safest or most economical option. Intravenous administration carries risks such as infection, phlebitis, and possible adverse reactions that need to be carefully monitored. Additionally, the cost of intravenous drug administration tends to be higher due to the need for specialized equipment and trained personnel.
Question 3 of 5
Which instruction(s) will the nurse include when teaching patients about gentamicin? (Select all that apply.)
Correct Answer: A
Rationale: Gentamicin is an aminoglycoside antibiotic associated with ototoxicity, which can manifest as hearing loss or tinnitus. Patients should be instructed to report any changes in hearing. Sunscreen is not specifically required for gentamicin, as it does not cause photosensitivity. Intravenous gentamicin is typically infused over 30-60 minutes, not 20 minutes. Monitoring for mouth ulcers and vaginitis is not a priority with gentamicin, but renal function and ototoxicity should be closely monitored.
Question 4 of 5
The nurse is discharging a 35-year-old patient with diabetes who has been prescribed an adrenergic blocking agent. What is the priority teaching point for the nurse to discuss with this patient?
Correct Answer: A
Rationale: It is important for the patient to be instructed to monitor blood sugar levels more frequently because adrenergic blocking agents mask the normal hypo- and hyperglycemic manifestations that normally alert patients such as sweating, feeling tense, increased heart rate, and rapid breathing. There is no need to change the diet or the diabetic medications. There may be no signs and symptoms to record because they are blocked by the adrenergic blocker. The nurse should emphasize the importance of frequent blood glucose monitoring and reporting any instability to the healthcare provider.
Question 5 of 5
A patient in the clinic reports difficulty tolerating the current ACE inhibitor medication, and questions if another medication could be used. The nurse correctly suspects the prescriber will choose which medication, which affects the renin-angiotensin-aldosterone system?
Correct Answer: B
Rationale: Losartan is an angiotensin II receptor blocker (ARB) that affects the renin-angiotensin-aldosterone system (RAAS) and is often used as an alternative to ACE inhibitors. Atenolol (A) is a beta-blocker, spironolactone (C) is a potassium-sparing diuretic, and adenosine (D) is used for arrhythmias. ARBs like losartan are preferred for patients who cannot tolerate ACE inhibitors due to side effects like cough or angioedema.
