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 client with ulcerative colitis has been prescribed sulfasalazine. The nurse should instruct the client to monitor for which of the following adverse effects of this medication?
- A. Jaundice
- B. Constipation
- C. Oral candidiasis
- D. Sedation
Correct Answer: A
Rationale: The correct answer is A: Jaundice. Sulfasalazine can cause liver damage as a possible adverse effect, which can manifest as jaundice. Monitoring for jaundice is crucial to detect liver-related adverse effects early. Choices B, C, and D are incorrect. Constipation, oral candidiasis, and sedation are not typically associated with sulfasalazine use. Therefore, the nurse should focus on educating the client specifically about monitoring for jaundice.
A client with a severe urinary tract infection (UTI) asks why both ciprofloxacin and phenazopyridine are needed. Which of the following responses should the nurse make?
- A. Phenazopyridine decreases adverse effects of ciprofloxacin.
- B. Combining phenazopyridine with ciprofloxacin shortens the course of therapy.
- C. The use of phenazopyridine allows for a lower dosage of ciprofloxacin.
- D. Ciprofloxacin treats the infection, and phenazopyridine treats pain.
Correct Answer: D
Rationale: Ciprofloxacin is an antibiotic that treats the infection, while phenazopyridine is a urinary analgesic that relieves pain. Choice A is incorrect because phenazopyridine does not decrease adverse effects of ciprofloxacin; it primarily addresses pain. Choice B is incorrect because combining phenazopyridine with ciprofloxacin does not shorten the course of therapy; they serve different purposes. Choice C is incorrect because the use of phenazopyridine does not allow for a lower dosage of ciprofloxacin; they have independent roles in UTI management.
A nurse is preparing to administer amoxicillin 250 mg liquid suspension PO every 8 hr to an older adult client. The amount available is amoxicillin 50 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number)
- A. 5 mL
- B. 6 mL
- C. 4 mL
- D. 7 mL
Correct Answer: A
Rationale: To calculate the amount of amoxicillin in mL needed per dose, we can use the formula: 50 mg/mL = 250 mg / X mL. Cross multiply to solve for X: 50X = 250. Divide both sides by 50 to find X, which equals 5 mL per dose. Therefore, the nurse should administer 5 mL of amoxicillin per dose. Choice B, 6 mL, is incorrect as it does not match the calculated result. Choice C, 4 mL, is incorrect as it is too low based on the calculation. Choice D, 7 mL, is incorrect as it is too high based on the calculation.
A nurse is preparing to administer heparin 8,000 units subcutaneously every eight hours. The amount available is heparin injection 10,000 units/mL. How many milliliters should the nurse administer per dose? (Round the answer to the nearest tenth)
- A. 0.8 mL
- B. 0.9 mL
- C. 10.0 mL
- D. 98.0 mL
Correct Answer: A
Rationale: To determine the volume of heparin to administer per dose, divide the prescribed dose (8,000 units) by the concentration of heparin available (10,000 units/mL). 8000 units / 10000 units/mL = 0.8 mL. Therefore, the nurse should administer 0.8 mL per dose. Choice B, 0.9 mL, is incorrect as the correct calculation results in 0.8 mL. Choices C and D are significantly higher and incorrect, indicating an inaccurate calculation.
