Question 1 of 5
A nurse is preparing to administer a daily dose of warfarin to a client. Which of the following laboratory values should the nurse check prior to administration?
Correct Answer: D
Rationale: The correct answer is D: INR. The International Normalized Ratio (INR) is a crucial laboratory value to monitor when administering warfarin, an anticoagulant. INR measures the effectiveness of warfarin therapy in preventing blood clots. Monitoring INR levels helps ensure the client is receiving the appropriate dose to achieve the desired anticoagulant effect while minimizing the risk of bleeding. Checking platelets (
A) is important for assessing clotting ability but not specific to warfarin therapy. The activated partial thromboplastin time (APTT) (
B) is more relevant for monitoring heparin therapy. White blood cell count (
C) is not directly related to warfarin therapy.
Question 2 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 commonly used to treat migraines by relieving headache symptoms. The absence of a headache indicates a therapeutic response to the medication.
A: Improved mood is not directly related to the therapeutic effect of sumatriptan.
B: Increased bone mass is not a known effect of sumatriptan.
C: Relief of chest pain is not a common indication for sumatriptan use.
Question 3 of 5
A nurse is reinforcing teaching with the parents of a 13-month-old child following administration of the measles, mumps, and rubella (MMR) immunization. Which of the following statements by the nurse is appropriate?
Correct Answer: A
Rationale:
Rationale:
Choice A is correct because the child will indeed receive another MMR immunization at 4 to 6 years of age as part of the standard immunization schedule. This ensures long-term protection.
Choice B is incorrect as the child does not need two more MMR immunizations over the next 2 years.
Choice C is incorrect because while the child may receive another MMR immunization at 3 years, there is no mention of hepatitis B immunization.
Choice D is incorrect as titers are not routinely done for MMR immunity assessment.
Question 4 of 5
A nurse is collecting data from a client who has been taking methimazole for 2 months for the treatment of a thyroid imbalance. Which of the following findings indicates that the medication is effective?
Correct Answer: B
Rationale: The correct answer is B: Weight gain. Methimazole is used to treat hyperthyroidism, which often leads to weight loss due to increased metabolism.
Therefore, weight gain would indicate that the medication is effective in normalizing the thyroid function. Increased libido (choice
A) is not a common indicator of the effectiveness of methimazole. Decreased menstrual flow (choice
C) might suggest hypothyroidism rather than improvement in hyperthyroidism. Clear breath sounds (choice
D) are not directly related to the effectiveness of methimazole in treating thyroid imbalance.
Question 5 of 5
A nurse is monitoring a client who is receiving a transfusion of packed RBCs. The nurse should identify which of the following findings as an indication of a febrile nonhemolytic reaction?
Correct Answer: D
Rationale: The correct answer is D: Chills. Febrile nonhemolytic reaction during a blood transfusion is characterized by the sudden onset of chills and fever. This occurs due to the recipient's immune system reacting to donor leukocytes. Dyspnea (
A) is more indicative of acute hemolytic reaction. Urticaria (
B) is associated with allergic reactions. Vomiting (
C) is not typically a sign of a febrile reaction. In summary, chills are the most specific finding for a febrile nonhemolytic reaction during a blood transfusion.
