Nursing Elites

1. A healthcare provider in an emergency unit is reviewing the medical record of a client who is being evaluated for angle-closure glaucoma. Which of the following findings are indicative of this condition?

• A. Insidious onset of painless loss of vision
• B. Gradual reduction in peripheral vision
• C. Severe pain around the eyes
• D. Intraocular pressure of 12mm Hg

Correct answer: C

Rationale: Severe pain around the eyes that radiates over the face is a characteristic symptom of acute angle-closure glaucoma. This intense pain is typically accompanied by other symptoms such as blurred vision, halos around lights, redness in the eye, and sometimes nausea and vomiting. The acute rise in intraocular pressure leads to these symptoms, indicating a medical emergency that requires immediate attention to prevent vision loss. Choices A, B, and D are incorrect. Insidious onset of painless loss of vision is more suggestive of conditions like age-related macular degeneration or diabetic retinopathy. Gradual reduction in peripheral vision is commonly seen in conditions like open-angle glaucoma. An intraocular pressure of 12mm Hg is within the normal range and not indicative of the acute rise seen in angle-closure glaucoma.

2. When caring for a client prescribed warfarin, which laboratory test should the nurse monitor to evaluate the therapeutic effect of the medication?

• A. aPTT
• B. Platelet count
• C. BUN
• D. PT/INR

Correct answer: D

Rationale: The correct laboratory test to monitor the therapeutic effect of warfarin is the PT/INR. Warfarin affects blood clotting, and the PT/INR levels indicate the effectiveness of the medication in preventing clot formation. Therefore, monitoring PT/INR levels helps ensure that the client is within the therapeutic range and is protected from potential complications related to clotting. Choice A (aPTT) is incorrect because while it measures the clotting time, it is not the preferred test for monitoring warfarin therapy. Choice B (Platelet count) is incorrect as it assesses the number of platelets and not the medication's therapeutic effect. Choice C (BUN) is unrelated to monitoring the effects of warfarin therapy and is primarily used to assess kidney function.

3. When educating a client who has a new prescription for Hydrochlorothiazide, which of the following statements should the nurse include?

• A. Take this medication in the morning.
• B. You may need to increase your intake of potassium.
• C. This medication may cause drowsiness.
• D. Avoid consuming grapefruit.

Correct answer: B

Rationale: The correct statement to include when educating a client with a new prescription for Hydrochlorothiazide is that they may need to increase their intake of potassium. Hydrochlorothiazide is a thiazide diuretic that can lead to potassium loss. Monitoring potassium levels and increasing potassium intake if necessary can help prevent complications associated with hypokalemia. Option A is not directly related to the medication's specific instructions. Option C is incorrect as Hydrochlorothiazide typically does not cause drowsiness. Option D is unrelated, as there is no interaction between Hydrochlorothiazide and grapefruit.

4. A client taking nitroglycerin (Nitrostat) for angina asks the nurse to explain possible side effects. What should NOT be included in client teaching?

• A. Reflex tachycardia
• B. Dizziness
• C. Hyponatremia
• D. Hypotension

Correct answer: C

Rationale: Hyponatremia is not a common side effect associated with nitroglycerin use. Nitroglycerin typically causes side effects such as reflex tachycardia, dizziness, and hypotension due to its vasodilatory effects. Therefore, it is important for the nurse to educate the client about these potential side effects to promote understanding and appropriate management.

5. What is the primary action of warfarin as an anticoagulant?

• A. Prevents the formation of blood clots
• B. Dissolves existing blood clots
• C. Dilates coronary arteries
• D. Treats rhythm disturbances

Correct answer: A

Rationale: The correct answer is A: "Prevents the formation of blood clots." Warfarin acts as an anticoagulant by inhibiting the synthesis of certain clotting factors in the liver. This action reduces the blood's ability to clot, making it effective in preventing the formation of blood clots. Choice B is incorrect because warfarin does not dissolve existing blood clots; it prevents their formation. Choice C is incorrect because warfarin's primary action is not to dilate coronary arteries. Choice D is incorrect as warfarin is not used to treat rhythm disturbances, but rather to prevent clot formation.
