Nursing Elites

1. A healthcare professional is assessing a client with severe dehydration. Which finding indicates a need for immediate intervention?

• A. Heart rate of 110 beats per minute.
• B. Blood pressure of 90/60 mm Hg.
• C. Urine output of 20 ml/hour.
• D. Dry mucous membranes.

Correct answer: C

Rationale: A urine output of 20 ml/hour indicates severe dehydration and impaired renal function. This finding suggests a critical state where the kidneys are conserving water, leading to reduced urine output. Immediate intervention is required to restore fluid balance and prevent further complications associated with severe dehydration. Choice A, a heart rate of 110 beats per minute, may indicate dehydration but is not as severe as the critically low urine output. Choice B, a blood pressure of 90/60 mm Hg, can be seen in dehydration but is not as concerning as the extremely low urine output. Choice D, dry mucous membranes, is a common sign of dehydration but does not require immediate intervention compared to the severely reduced urine output.

2. Prior to elective surgery, a patient taking warfarin should receive which instruction regarding warfarin therapy?

• A. Continue taking warfarin until the day of surgery.
• B. Stop taking warfarin three days before surgery.
• C. Switch to aspirin before surgery.
• D. Stop taking warfarin one week before surgery.

Correct answer: D

Rationale: Prior to elective surgery, a patient taking warfarin should be instructed to stop taking warfarin around one week before the procedure. This timeframe allows for the effects of warfarin to diminish, lowering the risk of excessive bleeding during surgery. Continuing warfarin until the day of surgery (Choice A) increases the risk of bleeding complications. Stopping warfarin three days before surgery (Choice B) may not provide enough time for the anticoagulant effects to subside. Switching to aspirin before surgery (Choice C) is not recommended as a substitute for warfarin in this context.

3. A 40-year-old woman 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 combination of symptoms including fatigue, polyuria, polydipsia, along with laboratory findings of hyperglycemia and ketonuria strongly suggest type 1 diabetes mellitus. In type 1 diabetes mellitus, there is a deficiency of insulin leading to high blood sugar levels (hyperglycemia) and the breakdown of fats producing ketones, causing ketonuria. Type 2 diabetes mellitus typically presents differently and is more common in older individuals. Diabetes insipidus is characterized by excessive thirst and urination due to a deficiency of antidiuretic hormone, distinct from the provided clinical scenario. Hyperthyroidism may present with some overlapping symptoms like fatigue, but it does not account for the specific laboratory findings of hyperglycemia and ketonuria seen in this case.

4. The nurse is planning care for a client with cirrhosis of the liver. Which intervention should the nurse include to reduce the risk of bleeding?

• A. Monitor for signs of infection.
• B. Limit the client's dietary protein intake.
• C. Administer vitamin K as prescribed.
• D. Encourage the client to increase fluid intake.

Correct answer: C

Rationale: Administering vitamin K as prescribed can help reduce the risk of bleeding in clients with cirrhosis by promoting clotting factor production. Cirrhosis often leads to impaired liver function, affecting the synthesis of clotting factors. Vitamin K supplementation helps in the production of these essential clotting factors, thus reducing the risk of bleeding in clients with cirrhosis. Monitoring for signs of infection (Choice A) is important for overall care but not directly related to reducing the risk of bleeding in cirrhosis. Limiting dietary protein intake (Choice B) may be necessary in some cases of cirrhosis but does not directly address the risk of bleeding. Encouraging increased fluid intake (Choice D) is beneficial for various aspects of health but does not specifically target the risk of bleeding in cirrhosis.

5. What assessments should the nurse prioritize for a client with portal hypertension admitted to the medical floor?

• A. Assessment of blood pressure and evaluation for headaches and visual changes
• B. Assessment for signs and symptoms of venous thromboembolism
• C. Daily weights and measurement of abdominal girth
• D. Monitoring blood glucose every 4 hours

Correct answer: C

Rationale: In portal hypertension, daily weights and measurement of abdominal girth are crucial assessments to monitor fluid retention and ascites. These assessments help in evaluating the effectiveness of treatment and identifying any worsening of the condition, guiding appropriate interventions. Monitoring blood pressure and assessing for symptoms like headaches and visual changes may be important but are not the priority in this case. Assessing for signs and symptoms of venous thromboembolism is relevant in some situations but not directly related to the primary concerns of portal hypertension.
