Nursing Elites

1. Warfarin (Coumadin) is an anticoagulant and interferes with the action of:

• A. Platelets
• B. Vitamin K
• C. Calcium
• D. Vitamin B12

Correct answer: B

Rationale: The correct answer is B: Vitamin K. Warfarin inhibits the action of vitamin K, which is essential for blood clotting. By interfering with the production of certain clotting factors, warfarin helps prevent blood clots. Choices A, C, and D are incorrect because warfarin primarily affects the vitamin K-dependent clotting factors and not platelets, calcium, or vitamin B12.

2. A 31-year-old client is seeking contraceptive information. Before responding to the client’s questions about contraceptives, the nurse obtains a health history. What factor in the client’s history indicates to the nurse that oral contraceptives are contraindicated?

• A. More than 30 years of age
• B. Had two multiple pregnancies
• C. Smokes 1 pack of cigarettes a day
• D. Has a history of borderline hypertension

Correct answer: C

Rationale: The correct answer is C. Smoking, especially in clients over 30, increases the risk of thromboembolic events, making oral contraceptives contraindicated. Choice A (More than 30 years of age) is not a direct contraindication for oral contraceptives. Choice B (Had two multiple pregnancies) is not a factor that contraindicates the use of oral contraceptives. Choice D (Has a history of borderline hypertension) is not a specific contraindication for oral contraceptives unless it is severe or uncontrolled hypertension.

3. A client scheduled for surgery cannot sign the operative consent form because he has been sedated with opioid analgesics. The nurse should take which best action regarding the informed consent?

• A. Obtain a court order for the surgery
• B. Sign the informed consent on behalf of the client
• C. Send the client to surgery without the consent form being signed
• D. Obtain a telephone consent from a family member, with the consent being witnessed by two healthcare providers

Correct answer: D

Rationale: In situations where a client is unable to sign the consent form, obtaining a telephone consent from a family member, with the consent being witnessed by two healthcare providers, is the best course of action. This ensures that the client's best interests are considered and that proper authorization is obtained. Option A, obtaining a court order, is not necessary in this scenario and could delay the surgery. Option B, signing the consent on behalf of the client, is not appropriate as it may raise ethical and legal concerns. Option C, sending the client to surgery without a signed consent form, is not advisable as it violates the principles of informed consent and places the client at risk.

4. Which electrolyte imbalance is a potential side effect of diuretics?

• A. Hyperkalemia
• B. Hypercalcemia
• C. Hypomagnesemia
• D. Hypokalemia

Correct answer: D

Rationale: The correct answer is D, Hypokalemia. Diuretics commonly cause hypokalemia due to increased urinary excretion of potassium. Hyperkalemia (Choice A) is the opposite, characterized by high potassium levels and is not typically associated with diuretics. Hypercalcemia (Choice B) is an elevated calcium level, which is not a common side effect of diuretics. Hypomagnesemia (Choice C) is low magnesium levels, which can be a side effect of diuretics, but the most common electrolyte imbalance associated with diuretics is hypokalemia.

5. In determining and fulfilling the nursing care needs of the patient, which step involves assessing whether the care provided is appropriate and effective in relation to the patient's current physiological and psychological status?

• A. Evaluation
• B. Planning
• C. Implementation
• D. Assessment

Correct answer: A

Rationale: The correct answer is A, 'Evaluation.' Evaluation in nursing involves assessing whether the care provided is appropriate and effective in relation to the patient's current physiological and psychological status. This step helps determine the outcomes of the care provided and if any changes are needed. Choice B, 'Planning,' focuses on developing a plan of care based on the assessment findings. Choice C, 'Implementation,' involves carrying out the plan of care. Choice D, 'Assessment,' is the initial step in the nursing process that involves gathering data about the patient's health status.
