Question 1 of 5
The following drug may be used safely in pregnancy:
Correct Answer: B
Rationale: Carbamazepine carries teratogenic risks (e.g., neural tube defects), making it unsafe in pregnancy. Digoxin is safe, used for fetal arrhythmias or maternal heart conditions, with no major congenital risks, a true statement. Streptomycin causes ototoxicity in the fetus, and methotrexate, a folate antagonist, is highly teratogenic, both unsafe. Propylthiouracil is also safe but not listed here correctly per the key. Digoxin's safety profile in pregnancy makes it a preferred option for cardiac issues, balancing maternal and fetal needs.
Question 2 of 5
Aspirin is ionized as it enters the small intestine. Which statement is accurate regarding the absorption of aspirin in the small intestine?
Correct Answer: A
Rationale: Aspirin, an acidic drug, ionizes in the small intestine's alkaline pH, reducing absorption as ionized forms cross membranes less easily than non-ionized. Absorption increases in the stomach's acid pH. Ionization directly affects rate. It absorbs mainly in the stomach and intestine, not beyond. Decreased absorption reflects pH impact, a pharmacokinetic rule.
Question 3 of 5
The patient is scheduled to have an EEG to confirm the presence of a sleep disorder. The patient asks the nurse to describe NREM stage 3 sleep. What is the best response by the nurse?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
The client's calcium level is low. What will be the nurse's primary concern?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
A 24-year-old G1P0 woman arrives at the hospital in labor at 39 weeks gestation. She denies an epidural, stating her desire to give birth naturally. After 5 h of labor, the baby has begun its descent through the birth canal when the patient requests pain relief. Which of the following opioids would be best to administer?
Correct Answer: A
Rationale: Labor pain relief without epidural favors Butorphanol , a mixed opioid agonist-antagonist. It provides analgesia with less respiratory depression risk to the fetus than Codeine , Methadone , or Morphine (E). Dextromethorphan is a cough suppressant. Butorphanol's safety profile suits late labor, minimizing neonatal impact.
