Question 1 of 5
Name the four categories of enteral formulas? (Select all that apply.)
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 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 3 of 5
Which drug combination is recommended for chronic hepatitis C infection?
Correct Answer: C
Rationale: Chronic hepatitis C (HCV) treatment targets viral clearance. Pegylated interferon alfa boosts immunity, lamivudine treats HBV, not HCV, so that's incorrect. Adefovir also targets HBV, not HCV. Pegylated interferon alfa with ribavirin, an antiviral, is a historical standard for HCV, enhancing sustained virologic response across genotypes, the recommended combo. Adefovir/lamivudine suits HBV, oseltamivir/zanamivir influenza. Ribavirin's synergy with interferon was key before direct-acting antivirals, effective for this condition.
Question 4 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 5 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.
