A nurse is planning to administer chlorothiazide 20 mg/kg/day PO divided equally and administered twice daily for a toddler who weighs 28.6 lb. The amount available is chlorothiazide oral suspension 250 mg/5 mL. How many mL should the nurse administer per dose? (Round to the nearest tenth)
- A. 2.6 mL
- B. 2.63 mL
- C. 2.7 mL
- D. 2.2 mL
Correct Answer: A
Rationale: To find the dose per administration, first convert the toddler's weight to kg: 28.6 lb · 2.2 = 13 kg. Then calculate the total daily dose: 20 mg/kg 13 kg = 260 mg/day. Since it is divided into two doses, each dose is 130 mg. The concentration of the oral suspension is 250 mg/5 mL = 50 mg/mL. Therefore, to find the volume needed per dose, divide the dose by the concentration: 130 mg · 50 mg/mL = 2.6 mL per dose. Hence, the nurse should administer 2.6 mL per dose. Choices B, C, and D are incorrect as they do not accurately calculate the dosage of chlorothiazide needed per dose based on the toddler's weight and the concentration of the oral suspension.

A client with congestive heart failure taking digoxin reports nausea and refuses to eat breakfast. Which action should the nurse take first?
- A. Encourage the client to eat the toast on the breakfast tray.
- B. Administer an antiemetic.
- C. Inform the client's provider.
- D. Check the client's apical pulse.
Correct Answer: D
Rationale: The correct action for the nurse to take first is to check the client's apical pulse. Nausea can be a sign of digoxin toxicity, and one of the early signs of digoxin toxicity is changes in the pulse rate. By checking the client's apical pulse, the nurse can assess if the digoxin level is too high. Encouraging the client to eat or administering an antiemetic may not address the underlying issue of digoxin toxicity. While informing the provider is important, assessing the client's condition through checking the apical pulse should be the immediate priority.
A nurse is providing teaching to a parent of a child who has asthma and a new prescription for a cromolyn sodium metered dose inhaler. Which of the following statements by the parent indicates the need for further teaching?
- A. I will give my child a dose as soon as wheezing starts.
- B. My child should rinse out his mouth after using the inhaler.
- C. My child should exhale completely before placing the inhaler in his mouth.
- D. If my child has difficulty breathing in the dose, a spacer can be used.
Correct Answer: A
Rationale: The correct answer is A. Cromolyn sodium is a preventive medication and should not be used as a rescue inhaler when wheezing starts. This indicates a need for further teaching as the parent should understand that cromolyn sodium is not meant for immediate relief of symptoms. Choice B is correct as rinsing the mouth after using the inhaler helps reduce the risk of oral thrush, a common side effect. Choice C is correct as exhaling completely before using the inhaler helps ensure proper inhalation of the medication. Choice D is correct as a spacer can be used if the child has difficulty coordinating breathing with the inhaler, improving medication delivery.
A nurse is caring for a client who has a new prescription for ergotamine. The nurse should recognize that ergotamine is administered to treat which of the following conditions?
- A. Raynaud's phenomenon
- B. Migraine headaches
- C. Ulcerative colitis
- D. Anemia
Correct Answer: B
Rationale: Ergotamine is used to treat migraine headaches by constricting blood vessels in the brain. Therefore, the correct answer is B. Choice A, Raynaud's phenomenon, is incorrect as ergotamine is not indicated for this condition. Choice C, Ulcerative colitis, is incorrect as ergotamine is not used to treat this gastrointestinal disorder. Choice D, Anemia, is incorrect as ergotamine is not prescribed for anemia.
A nurse is providing teaching to a newly licensed nurse about administering morphine via IV bolus to a client. Which of the following information should the nurse include in the teaching?
- A. Respiratory depression can occur within 7 minutes after the morphine is administered.
- B. The morphine will peak within a few minutes.
- C. Withhold the morphine if the client has a respiratory rate less than 16/min.
- D. Administer the morphine over 2 minutes.
Correct Answer: A
Rationale: The correct answer is A because respiratory depression is a significant risk when administering morphine, and it can occur within 7 minutes after administration. This information is crucial for the nurse to recognize and respond promptly. Choice B is incorrect because the peak effect of morphine via IV bolus is typically reached within a few minutes, not specifically 10 minutes. Choice C is incorrect because withholding morphine based solely on a respiratory rate less than 16/min may not be appropriate without considering other factors such as pain level, oxygen saturation, and overall respiratory status. Choice D is incorrect because administering morphine over 2 minutes may not prevent respiratory depression if it occurs rapidly after administration. Nurses should be vigilant for signs of respiratory depression regardless of the administration duration.
A nurse is caring for a client who has a new prescription for tamoxifen. The nurse should recognize that tamoxifen has which of the following therapeutic effects?
- A. Antiestrogenic
- B. Antimicrobial
- C. Androgenic
- D. Anti-inflammatory
Correct Answer: A
Rationale: Tamoxifen is an antiestrogen medication used primarily in the treatment and prevention of breast cancer. It works by blocking the effects of estrogen in the breast tissue, thereby acting as an antiestrogenic agent. This makes choice A the correct answer. Choice B, antimicrobial, is incorrect as tamoxifen does not possess antimicrobial properties and is not used to treat infections. Choice C, androgenic, is incorrect as tamoxifen has antiestrogenic effects, not androgenic effects. Choice D, anti-inflammatory, is incorrect as tamoxifen's main therapeutic action is antiestrogenic rather than anti-inflammatory.
