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 preparing to administer insulin lispro to a client who has type 1 diabetes mellitus. Which of the following actions should the nurse plan to take?
Correct Answer: A
Rationale: The correct answer is A: Inject insulin lispro 15 min before a meal. This is because insulin lispro is a rapid-acting insulin that should be administered within 15 minutes before a meal to control postprandial glucose levels effectively. Administering it before a meal ensures that the insulin peaks when the client's blood glucose levels rise after eating, thus preventing hyperglycemia. Monitoring for polyuria (choice
B) is important but not specific to insulin lispro administration. Checking the expiration date (choice
C) is necessary but not directly related to the administration process. Administering insulin without washing the syringe (choice
D) is incorrect as proper hygiene is essential to prevent infections.
Question 3 of 5
A nurse is preparing to administer lorazepam 2 mg PO. Available in lorazepam 1 mg tablets. How many tablets should the nurse administer?
Correct Answer: B
Rationale: The correct answer is B: 2 tablets. The nurse needs to administer 2 mg of lorazepam, and each tablet is 1 mg.
Therefore, to achieve the total dose of 2 mg, the nurse should administer 2 tablets. Administering 1 tablet (choice
A) would only provide 1 mg, which is insufficient.
Choices C and D would exceed the required dose of 2 mg, leading to potential overdose and adverse effects.
Question 4 of 5
A nurse is preparing to administer Lactated Ringer's solution IV to infuse at 120 mL/hr for a client who has a respiratory disorder. The drop factor in the manual IV tubing is 60 gtt/mL. The nurse should set the flow rate to deliver how many gtts/min?
Correct Answer: C
Rationale: The correct answer is C: 120 gtt/min.
To calculate the infusion rate in gtts/min, first convert the prescribed rate of 120 mL/hr to gtts/hr by multiplying it by the drop factor of 60 gtt/mL.
120 mL/hr * 60 gtt/mL = 7200 gtts/hr
Next, convert gtts/hr to gtts/min by dividing by 60 (since there are 60 minutes in an hour):
7200 gtts/hr / 60 min = 120 gtts/min
Therefore, the nurse should set the flow rate to deliver 120 gtts/min.
Choice A is incorrect as it is lower than the correct answer.
Choice B is incorrect as it is also lower than the correct answer.
Choice D is incorrect as it is higher than the correct answer.
Question 5 of 5
A nurse administers subcutaneous NPH insulin at 0700 to a child who has diabetes. At which of the following times should the nurse observe for hypoglycemia caused by the onset of the medication?
Correct Answer: D
Rationale: The correct answer is D: 1000. NPH insulin typically starts working within 1 to 2 hours after administration, peaks in 4 to 12 hours, and lasts up to 24 hours. Since the nurse administered the insulin at 0700, the onset of hypoglycemia should be observed around 0900 to 1100.
Choice A (715) is too soon for onset.
Choice B (800) falls within the expected onset time, but it may be too early for hypoglycemia.
Choice C (900) is also within the expected onset time frame, but waiting until 1000 (
Choice
D) allows for a more accurate observation of hypoglycemia as the peak effect of NPH insulin is approaching.
