Question 1 of 5
A nurse is collecting data from a client who is taking sumatriptan. Which of the following reports indicates a therapeutic response to the medication?
Correct Answer: D
Rationale: The correct answer is D: Absence of headache. Sumatriptan is a medication used to treat migraines. A therapeutic response would be the absence of headache, as this indicates that the medication is effectively managing the migraine symptoms. Increased bone mass (
A) is unrelated to sumatriptan. Relief of chest pain (
B) is not a common indication of sumatriptan. Improved mood (
C) is not a direct effect of sumatriptan.
Therefore, the absence of headache (
D) is the most relevant and expected therapeutic response to sumatriptan.
Question 2 of 5
A nurse is reinforcing teaching about the pledge program with a female client who has a new prescription for…. The nurse should tell the client that which of the following is a requirement of the program?
Correct Answer: C
Rationale: The correct answer is C: Sexually active female clients must use two forms of birth control during treatment. This requirement is crucial to prevent pregnancy while on the medication, which could harm the fetus. A Papanicolaou test every 6 months (
Choice
A) is important for monitoring cervical health but not a requirement of the program. Starting a daily supplement of vitamin A (
Choice
B) is not directly related to the program's requirements. A negative mammogram (
Choice
D) is not necessary for the program.
Question 3 of 5
A nurse is preparing to administer gentamicin to a child who weighs 44 lb. The provider prescribes 6 mg/kg/day IV to be administered in three equal doses. Available is gentamicin 40 mg/mL. How many mL should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 1 mL
Rationale:
Rationale:
To calculate the dose per administration, first convert the child's weight to kg (44 lb ÷ 2.2 = 20 kg).
Then multiply the weight by the prescribed dose (20 kg × 6 mg/kg/day = 120 mg/day). Divide the total daily dose by the number of doses (120 mg ÷ 3 doses = 40 mg per dose). Finally, divide the dose needed by the concentration of gentamicin available (40 mg ÷ 40 mg/mL = 1 mL per dose).
Therefore, the correct answer is 1 mL. Other choices are incorrect as they do not align with the accurate calculation derived from the prescription and weight of the child.
Question 4 of 5
A nurse is caring for a client who reports muscle spasms after receiving haloperidol. Which of the following medications should the nurse expect to administer?
Correct Answer: B
Rationale: The correct answer is B: Benztropine. Benztropine is an anticholinergic medication used to treat extrapyramidal symptoms like muscle spasms caused by antipsychotic medications like haloperidol. It works by blocking excess acetylcholine in the brain. Metoprolol (
A) is a beta-blocker used for blood pressure, not muscle spasms. Oxycodone (
C) is an opioid for pain relief. Risperidone (
D) is another antipsychotic, not for treating spasms.
Question 5 of 5
A nurse is assisting in the development of an in-service about the varicella vaccine. The nurse should include which of the following examples as a contraindication for receiving the vaccine?
Correct Answer: D
Rationale: The correct answer is D: A client who is pregnant. Varicella vaccine is contraindicated during pregnancy due to the potential risk of harm to the fetus. The live attenuated vaccine may pose a theoretical risk of causing harm to the developing fetus. It is recommended that women avoid becoming pregnant for at least one month after receiving the varicella vaccine.
A: Breastfeeding is not a contraindication for the varicella vaccine. In fact, breastfeeding is encouraged after receiving the vaccine.
B: Having an allergy to latex is not a contraindication for the varicella vaccine.
C: Having a sinus infection is not a contraindication for the varicella vaccine.
E, F, G: No information given, so they cannot be evaluated.
