Nursing Elites

1. A client receiving warfarin (Coumadin) therapy should have which of the following laboratory results reviewed to evaluate the effectiveness of the therapy?

• A. Complete blood count (CBC).
• B. Prothrombin time (PT).
• C. International normalized ratio (INR).
• D. Partial thromboplastin time (PTT).

Correct answer: C

Rationale: The correct answer is C: International normalized ratio (INR). The INR is the most appropriate laboratory result to review when evaluating the effectiveness of warfarin (Coumadin) therapy. Warfarin is an anticoagulant medication, and the INR helps determine if the dosage is within a therapeutic range to prevent clotting or bleeding complications. Choice A, a Complete Blood Count (CBC), provides information about the cellular components of blood but does not directly assess the anticoagulant effects of warfarin. Choice B, Prothrombin time (PT), measures the time it takes for blood to clot but is not as specific for monitoring warfarin therapy as the INR. Choice D, Partial Thromboplastin Time (PTT), evaluates the intrinsic pathway of coagulation and is not the primary test used to monitor warfarin therapy.

2. In a patient with chronic kidney disease, which of the following is a common electrolyte imbalance?

• A. Hyperkalemia.
• B. Hypokalemia.
• C. Hypernatremia.
• D. Hyponatremia.

Correct answer: A

Rationale: Hyperkalemia is a common electrolyte imbalance in chronic kidney disease. In chronic kidney disease, the kidneys' reduced function leads to the decreased excretion of potassium, resulting in elevated serum potassium levels. This can be dangerous as hyperkalemia can lead to life-threatening arrhythmias. Hypokalemia (Choice B) is less common in chronic kidney disease as the impaired kidneys tend to retain potassium. Hypernatremia (Choice C) is more commonly seen in conditions such as dehydration, not primarily in chronic kidney disease. Hyponatremia (Choice D) is also possible in chronic kidney disease but is less common compared to hyperkalemia.

3. A client with chronic renal failure is receiving calcium acetate (PhosLo). The nurse should monitor the client for which of the following side effects?

• A. Hypercalcemia.
• B. Hypocalcemia.
• C. Hyperglycemia.
• D. Hypoglycemia.

Correct answer: A

Rationale: Corrected Question: A client with chronic renal failure is receiving calcium acetate (PhosLo). The nurse should monitor the client for which of the following side effects? Rationale: The correct answer is A, Hypercalcemia. Calcium acetate (PhosLo) is a medication used to lower phosphate levels in patients with chronic renal failure. It works by binding with dietary phosphate and preventing its absorption. However, this can lead to an excess of calcium in the blood, causing hypercalcemia. Therefore, the nurse should closely monitor the client for signs and symptoms of elevated calcium levels, such as nausea, vomiting, confusion, and muscle weakness. Choices B, C, and D are incorrect as calcium acetate does not typically cause hypocalcemia, hyperglycemia, or hypoglycemia.

4. The nurse is providing discharge instructions to a client who is receiving prednisone 5 mg PO daily for a rash due to contact with poison ivy. Which symptoms should the nurse tell the client to report to the healthcare provider?

• A. Rapid weight gain
• B. Abdominal striae
• C. Moon faces
• D. Gastric irritation

Correct answer: A

Rationale: Rapid weight gain can indicate fluid retention, which is a serious side effect of prednisone and should be reported.

5. A client is scheduled to have an arteriogram. During the arteriogram, the client reports having nausea, tingling, and dyspnea. The nurse's immediate action should be to:

• A. Administer epinephrine.
• B. Inform the physician.
• C. Administer oxygen.
• D. Inform the client that the procedure is almost over.

Correct answer: B

Rationale: The correct immediate action for the nurse to take in this situation is to inform the physician. The symptoms described - nausea, tingling, and dyspnea - indicate a potential allergic reaction to the contrast dye used in the arteriogram. It is crucial to notify the physician promptly so that further assessment and appropriate interventions can be initiated. Administering epinephrine without physician guidance can be dangerous as the physician needs to evaluate the severity of the reaction and determine the necessary treatment. Administering oxygen may be needed but should be done under the physician's direction. Informing the client that the procedure is almost over is not a priority when the client is experiencing symptoms of a possible allergic reaction.
