Question 1 of 5
A nurse in a provider's office is collecting data from a client who has hypothyroidism. Which of the following should the nurse expect?
Correct Answer: A
Rationale: The correct answer is A: Bradycardia. In hypothyroidism, there is a decrease in thyroid hormone production, leading to a slowed metabolism. This results in bradycardia, or a slow heart rate, as the thyroid hormone plays a role in regulating heart function. Moist skin (
B), blurred vision (
C), and insomnia (
D) are not typically associated with hypothyroidism; instead, dry skin, vision changes, and fatigue are more common symptoms.
Question 2 of 5
A nurse is teaching a newly licensed nurse about insulin storage. Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?
Correct Answer: A,B
Rationale:
Correct
Answer: A, B
Rationale:
A: Storing the current vial of insulin in use at room temperature is correct as it can be kept at room temperature for up to 28 days for most types of insulin, ensuring easy access and proper storage.
B: Storing unopened vials of insulin in the refrigerator is correct to maintain their efficacy and stability, preventing exposure to heat or light that can degrade the insulin.
C: Discarding the current vial of insulin after six doses have been taken is incorrect as insulin vials can typically be used for multiple doses as long as they are stored properly.
D: Returning unused vials of insulin to the healthcare provider's office for disposal is unnecessary and does not relate to insulin storage guidelines.
Summary:
Choices C and D are incorrect as they do not align with the proper storage guidelines for insulin.
Choice A and B demonstrate an understanding of insulin storage requirements.
Question 3 of 5
A nurse in the emergency department is assisting with the care of a client who has a deep laceration on her left lower forearm and is bleeding heavily from the wound. Which of the following actions should the nurse take first?
Correct Answer: C
Rationale: The correct action is to apply pressure directly to the wound first. This is crucial to control the bleeding and prevent further blood loss. Applying pressure helps to promote clotting and reduce the risk of hypovolemic shock. It is the immediate and most effective intervention to manage the situation.
Choice A (Apply a tourniquet just above the wound) is incorrect because tourniquets should be used as a last resort due to the risk of tissue damage and potential complications.
Choice B (Place the client in a modified Trendelenburg position) is incorrect as this position is not recommended for patients with bleeding as it can increase intracranial pressure and worsen the situation.
Choice D (Settle the client in a reclining position) is incorrect because the priority is to control the bleeding first before adjusting the client's position.
Question 4 of 5
A nurse is preparing to administer levothyroxine 100mcg po to a client who has hypothyroidism. Available levothyroxine is 50 mcg tablets. How many tablets should the nurse administer? (Round off to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: B
Rationale:
To determine the number of tablets to administer, divide the prescribed dose by the available dose per tablet. In this case, 100mcg ÷ 50mcg = 2 tablets. The correct answer is B because administering 2 tablets of 50mcg each will provide the total prescribed dose of 100mcg.
Choice A is incorrect as it would only provide 50mcg, while choices C and D would exceed the prescribed dose.
Choices E, F, and G are not applicable.
Question 5 of 5
Which of the following statements indicates that the client understands the effects of warfarin (coumadin)?
Correct Answer: A
Rationale: The correct answer is A because using an electric razor for shaving indicates the client understands the risk of bleeding while on warfarin (coumadin) due to its anticoagulant effects. Shaving with a manual razor can increase the risk of cuts and bleeding.
Choice B is incorrect because aspirin is a blood thinner and should not be taken with warfarin as it can increase the risk of bleeding.
Choice C is incorrect as vitamin K-rich foods can interfere with the effectiveness of warfarin.
Choice D is incorrect because alcohol can also interact with warfarin and increase the risk of bleeding.
