Question 1 of 5
Which assessment finding indicates that the patient is at risk from polypharmacy? (Select all that apply.)
Correct Answer: A,B
Rationale: Multiple pharmacies (
A) increase polypharmacy risk due to potential duplication or interactions from lack of centralized oversight. Five hypertension drugs (
B) signal excessive medications for one condition, heightening interaction risks. Daughter’s help (
C) aids compliance, warfarin tests (
D) manage one drug safely, and allergies (E) affect drug choice, not quantity.
Question 2 of 5
Why does the nurse administer lorazepam intramuscularly (IM) to the patient rather than into the subcutaneous tissue?
Correct Answer: C
Rationale: Body fat levels influence subcutaneous absorption but are not the primary reason for choosing IM over SC injection in this scenario. Needle size varies by medication and patient factors, but this is not the defining reason for selecting IM over SC injection. IM injections deliver medication directly to muscle tissue with a rich vascular supply, ensuring faster absorption and onset compared to subcutaneous administration. IM injections are not inherently safer for patients at risk of bleeding; they carry similar risks and require proper assessment before administration.
Question 3 of 5
After the nurse hands a client a medication, the client says, 'What is this red tablet for? I have always taken a yellow pill.' What is the most appropriate action for the nurse to take?
Correct Answer: A
Rationale: Withholding and rechecking ensures safety; a color change signals a potential error, and verifying the MAR against orders prevents administering the wrong drug. Assuming a change is risky; without confirmation, administering an unverified drug could harm the patient if it's not the intended prescription. Administering then checking later endangers the patient; a wrong drug could cause adverse effects, and delayed verification violates safety protocols. Describing and giving without verification is unsafe; the red tablet may not match the order, risking incorrect treatment or allergic reactions.
Question 4 of 5
The physician orders Salagen 10 mg po twice a day for dry eyes. The medication is supplied in 5-mg tablets. How many tablets will the nurse administer?
Correct Answer: B
Rationale: One 5-mg tablet delivers 5 mg; this underdoses the 10 mg ordered, reducing salivation stimulation needed for dry eye relief. Two 5-mg tablets equal 10 mg; this matches the order, ensuring therapeutic cholinergic effect to increase tear production effectively. Three tablets (15 mg) overdose; excess pilocarpine risks side effects (e.g., sweating, bradycardia) without added benefit for dry eyes. Four tablets (20 mg) far exceed the dose; this could cause severe cholinergic toxicity, including respiratory distress, outweighing therapeutic intent.
Question 5 of 5
The technique in which the practitioner alters body energy fields by passing his hands over the patient to determine where tensions exist is the practice of:
Correct Answer: D
Rationale: Biofeedback uses devices to monitor physiological signals (e.g., heart rate); it doesn't involve hands altering energy fields, focusing on self-regulation instead. Allopathic is conventional medicine (e.g., drugs, surgery); it relies on empirical science, not energy field manipulation, differing from the described technique. Imagery involves mental visualization for relaxation; it's cognitive, not physical, and lacks the hands-on energy assessment central to the practice. Therapeutic touch uses hand passes to sense and adjust energy fields; it aims to reduce tension, aligning precisely with the described holistic method.
