Nursing Elites

1. A client with a history of deep vein thrombosis (DVT) is receiving warfarin (Coumadin). Which laboratory value indicates a therapeutic effect of the medication?

• A. INR of 2.5.
• B. PTT of 45 seconds.
• C. Hemoglobin of 12 g/dL.
• D. Platelet count of 150,000/mm³.

Correct answer: A

Rationale: An INR (International Normalized Ratio) of 2.5 indicates a therapeutic level for clients receiving warfarin (Coumadin) to prevent thromboembolism. It is essential to monitor INR levels regularly when on warfarin therapy to ensure that the blood's ability to clot is within the desired range to prevent both clotting and excessive bleeding.

2. A client with a history of hypertension is prescribed lisinopril (Prinivil). Which side effect should the nurse monitor for?

• A. Dry cough.
• B. Weight gain.
• C. Tachycardia.
• D. Hyperglycemia.

Correct answer: A

Rationale: The correct answer is A: Dry cough. Lisinopril is an ACE inhibitor, and a common side effect of ACE inhibitors is a dry cough. This occurs due to the accumulation of bradykinin in the lungs, leading to irritation and subsequent cough. It is important for the nurse to monitor the client for this side effect as it can affect adherence to the medication regimen. Weight gain, tachycardia, and hyperglycemia are not typically associated with lisinopril. Therefore, choices B, C, and D are incorrect.

3. What health promotion teaching should prioritize to prevent drug-induced hepatitis?

• A. Finish all prescribed courses of antibiotics, regardless of symptom resolution
• B. Adhere to dosing recommendations of over-the-counter analgesics
• C. Ensure that expired medications are disposed of safely
• D. Ensure that pharmacists regularly review drug regimens for potential interactions

Correct answer: B

Rationale: Adhering to dosing recommendations of over-the-counter analgesics is crucial in preventing drug-induced hepatitis. Overdosing on analgesics can lead to liver damage, making it essential to follow the recommended dosages to reduce the risk of hepatotoxicity.

4. A 60-year-old man presents with fatigue, polyuria, and polydipsia. Laboratory tests reveal hyperglycemia and ketonuria. What is the most likely diagnosis?

• A. Type 1 diabetes mellitus
• B. Type 2 diabetes mellitus
• C. Diabetes insipidus
• D. Hyperthyroidism

Correct answer: A

Rationale: The presentation of a 60-year-old man with fatigue, polyuria, polydipsia, hyperglycemia, and ketonuria strongly suggests type 1 diabetes mellitus. Type 1 diabetes typically presents with acute symptoms due to absolute insulin deficiency, leading to hyperglycemia and ketonuria. Conversely, type 2 diabetes often presents more insidiously and is associated with relative insulin deficiency and insulin resistance. Diabetes insipidus, a condition characterized by excessive thirst and excretion of large amounts of dilute urine, is due to problems with antidiuretic hormone (ADH) and is not associated with hyperglycemia or ketonuria. Hyperthyroidism, while also presenting with symptoms like fatigue, does not typically manifest with hyperglycemia or ketonuria. Therefore, based on the clinical presentation and laboratory findings, the most likely diagnosis in this case is type 1 diabetes mellitus.

5. The patient has a calcium level of 12.1 mg/dL. Which nursing action should the nurse include on the care plan?

• A. Maintain the patient on bed rest.
• B. Auscultate lung sounds every 4 hours.
• C. Monitor for Trousseau's and Chvostek's signs.
• D. Encourage fluid intake up to 4000 mL every day.

Correct answer: D

Rationale: The correct action for the nurse to include on the care plan for a patient with a calcium level of 12.1 mg/dL is to encourage fluid intake up to 4000 mL every day. This is essential to decrease the risk for renal calculi associated with hypercalcemia. While bed rest is not necessary, ambulation is encouraged to help decrease the loss of calcium from the bone. Monitoring for Trousseau's and Chvostek's signs is more relevant when hypocalcemia is suspected. Auscultating lung sounds every shift is a routine assessment, not required every 4 hours unless there is a specific respiratory concern.
