Question 1 of 5
A client is receiving miotics for the treatment of open-angle glaucoma. The nurse determines that a priority nursing problem is a 'Risk for injury' and this is based on which etiology? Which etiology is the basis for the 'Risk for injury' nursing problem?
Correct Answer: B
Rationale: Miotics constrict the pupil, reducing light entry and impairing night vision, which increases the risk of injury in low-light conditions. This etiology directly supports the 'Risk for injury' nursing problem.
Question 2 of 5
A client receives a prescription for a secondary infusion of IV erythromycin 1 gram in 200 mL dextrose 5% in water (D5W) to be infused in 90 minutes. The nurse should program the infusion pump to deliver how many mL/hour? (Enter the numerical value only. If rounding is required, round to the nearest whole number.) The nurse should program the infusion pump to deliver how many mL/hour?
Correct Answer: 133
Rationale: Volume = 200 mL; time = 90 minutes = 1.5 hours; infusion rate = 200 mL ÷ 1.5 hours = 133.33 mL/hr, rounded to 133 mL/hr.
Question 3 of 5
A young adult female client who is planning to become pregnant asks the nurse if she can continue taking isotretinoin for cystic acne. Which information is most important for the nurse to provide this client? Which information is most important for the nurse to provide this client?
Correct Answer: D
Rationale: Isotretinoin is highly teratogenic, posing severe risks of fetal abnormalities. Discontinuing the medication at least one month before conception ensures it is cleared from the body, preventing harm to the fetus.
Question 4 of 5
A client with peptic ulcer disease (PUD) is scheduled to receive doses of pantoprazole IV and sucralfate PO before breakfast at 0730. The client reports experiencing heartburn when the nurse brings the scheduled medications. Which action should the nurse take? Which action should the nurse take?
Correct Answer: D
Rationale: Pantoprazole reduces acid production, and sucralfate forms a protective barrier over ulcers, both most effective when given before meals. Administering both as scheduled addresses heartburn and promotes ulcer healing.
Question 5 of 5
Before administering the initial dose of sumatriptan succinate to a client with a migraine headache, it is most important to determine if the client's history includes which problem? Which problem in the client's history is most important to determine?
Correct Answer: B
Rationale: Sumatriptan, a triptan, causes vasoconstriction, which can precipitate myocardial ischemia in clients with coronary artery disease. Checking for this condition prevents serious cardiovascular events.
