Question 1 of 5
The following drugs can induce malignant hyperthermia:
Correct Answer: B
Rationale: Succinylcholine is a trigger for malignant hyperthermia in susceptible individuals due to its effects on calcium release in muscle cells.
Question 2 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 3 of 5
Orthostatic hypotension is a common side e昀昀ect in which of these drugs (select all that apply)?
Correct Answer: A
Rationale: Orthostatic hypotension is a common side effect seen in ACE Inhibitors, Beta Blockers, and Calcium Channel Blockers.
Question 4 of 5
What action is often recommended to help reduce tolerance to transdermal nitroglycerin therapy?
Correct Answer: A
Rationale: Omitting a dose of transdermal nitroglycerin therapy once a week is often recommended to help reduce tolerance. Tolerance to nitroglycerin can develop with continuous use, limiting its effectiveness. By omitting a dose once a week, you are essentially giving the body a break from the medication and preventing tolerance from developing. This strategy can help maintain the efficacy of the nitroglycerin therapy over time. It is important to follow the guidance of a healthcare provider when making any changes to the dosing regimen of nitroglycerin to ensure safety and effectiveness.
Question 5 of 5
The nurse is managing the care of a group of patients with schizophrenia. The patients are receiving conventional antipsychotic medications. When assessing for anticholinergic side effects, which would the nurse immediately report to the physician?
Correct Answer: D
Rationale: Conventional antipsychotics (e.g., haloperidol) cause anticholinergic effects like urinary retention , a potential emergency risking bladder damage, requiring immediate reporting. Dystonia is extrapyramidal, not anticholinergic. Headache and hypertension aren't typical anticholinergic signs. D prioritizes urgent intervention, making it the correct choice.
