Question 1 of 5
A nurse is preparing to administer a levothyroxine 50 mcg tablet PO to a client who is receiving an enteral feeding through an NG tube. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: Dissolving levothyroxine in 30 mL of water ensures it's suitable for NG tube administration and prevents clogging. Supine positioning risks aspiration, mixing with formula can reduce efficacy, and 5 mL is insufficient to clear the tube (15-30 mL is standard).
Question 2 of 5
A nurse is collecting data from a client who received diphenhydramine 1 hr ago after developing an allergic reaction to trimethoprim-sulfamethoxazole. Which of the following statements by the client should indicate to the nurse that the medication is effective?
Correct Answer: A
Rationale: A no-longer-hoarse voice indicates diphenhydramine has reduced throat swelling from the allergic reaction, showing effectiveness. Alertness contradicts its sedative effect, and headache or appetite changes are not primary indicators.
Question 3 of 5
A nurse is collecting data from a client who received levalbuterol 30 min ago. Which of the following findings should the nurse identify as a therapeutic effect of the medication?
Correct Answer: A
Rationale: Levalbuterol, a bronchodilator, reduces wheezing by relaxing airway muscles, its primary therapeutic effect. Increased respiratory rate or heart rate are side effects, and it doesn't treat nausea.
Question 4 of 5
A nurse working in an urgent care clinic is collecting data from a client who takes montelukast. Which of the following is an expected therapeutic effect of this medication?
Correct Answer: D
Rationale: Montelukast, a leukotriene inhibitor, reduces bronchial inflammation in asthma, its primary therapeutic effect. It doesn't affect vasodilation, WBC count, or gastric acid.
Question 5 of 5
A nurse is reinforcing teaching about the iPLEDGE program with a female client who has a new prescription for isotretinoin. The nurse should tell the client that which of the following is a requirement of the program?
Correct Answer: D
Rationale: The iPLEDGE program requires sexually active female clients to use two forms of birth control due to isotretinoin's severe teratogenic effects. Mammograms, Pap tests, and vitamin A supplements are not part of this program's requirements.
