Question 1 of 5
A student nurse was asked by the nurse instructor to explain the procedure for the administration of erythromycin ointment to the eyes of the newborn. Which of the following statements made by the student indicates a need for further research?
Correct Answer: D
Rationale: Flushing the newborn's eyes after instilling erythromycin ointment is incorrect because it would remove the medication, rendering it ineffective. The ointment is applied to the conjunctival sacs to prevent ophthalmia neonatorum, a bacterial infection that can occur during delivery. Cleaning the eyes before administration and applying the ointment within an hour after delivery are correct steps. Therefore, the statement about flushing the eyes indicates a need for further education.
Question 2 of 5
With regard to non-depolarising neuromuscular blocking drugs:
Correct Answer: A
Rationale: Pancuronium is primarily renally eliminated, a true statement, prolonged in kidney failure. Rocuronium, a steroidal agent, not isoquinolone (like atracurium), is false. Rocuronium is hepatically metabolized, not via Hofmann elimination (atracurium does), so that's false. Vecuronium is mostly biliary excreted, not renal, making that false. Atracurium uses plasma esterases and Hofmann elimination, not pseudocholinesterases alone. Pancuronium's renal clearance is critical for surgical planning, especially in renal patients.
Question 3 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 4 of 5
The patient and his wife receive the same medication for hypertension. The patient's wife asks the nurse why she is receiving a higher amount of the medication. What is the best response by the nurse?
Correct Answer: B
Rationale: Individual variation-metabolism, weight, genetics-dictates dose differences, a pharmacokinetic truth explaining her higher amount. Female metabolism isn't universally higher. Hormones affect response, but not broadly dose. Body fat impacts distribution, not directly dose here. Uniqueness covers all factors, reassuring and accurate.
Question 5 of 5
Benzodiazepines are often the drug of choice for managing anxiety and insomnia. Which statement best explains why?

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
