Nursing Elites

1. Which laboratory results should the nurse anticipate to be abnormal in a child with hemophilia?

• A. Prothrombin time
• B. Bleeding time
• C. Platelet count
• D. Partial thromboplastin time

Correct answer: D

Rationale: In a child with hemophilia, the nurse should anticipate an abnormality in the partial thromboplastin time (PTT) due to the deficiency in clotting factors. Prothrombin time, bleeding time, and platelet count are typically normal in hemophilia. Prothrombin time measures the extrinsic pathway of coagulation and is not affected in hemophilia. Bleeding time assesses platelet function, which is normal in hemophilia as the issue lies with clotting proteins, not platelets. Platelet count is also expected to be normal unless there is another underlying condition affecting platelet production or function.

2. A male client with muscular dystrophy fell in his home and is admitted with a right hip fracture. His right foot is cool, with palpable pedal pulses. Lungs are coarse with diminished bibasilar breath sounds. Vital signs are temperature 101 degrees F, heart rate 128 beats/minute, respirations 28 breaths/minute, and blood pressure 122/82. Which intervention is most important for the nurse to implement first?

• A. Obtain oxygen saturation level.
• B. Encourage incentive spirometry.
• C. Assess lower extremity circulation
• D. Administer PRN oral antipyretic.

Correct answer: D

Rationale: Administering an antipyretic is the most important intervention. The client presents with an elevated temperature, tachycardia, and tachypnea, indicating a fever. Lowering the temperature with an antipyretic is crucial to prevent complications like dehydration, altered mental status, and increased oxygen demand. While assessing lower extremity circulation and oxygen saturation are important, addressing the elevated temperature takes priority in this scenario. Incentive spirometry may be beneficial but is not the priority compared to managing the fever.

3. A middle-aged man who has a 35-year smoking history presents to the emergency department confused and short of breath. Before starting oxygen, these baseline arterial blood gases (ABGs) are obtained: pH=7.25, pCO2=50 mmHg, HCO3=30 mEq/L. These findings indicate to the nurse that the client is experiencing which acid-base imbalance?

• A. Metabolic acidosis.
• B. Respiratory acidosis.
• C. Metabolic alkalosis.
• D. Respiratory alkalosis.

Correct answer: B

Rationale: The ABG results show a low pH (acidosis) and increased pCO2, indicating respiratory acidosis. In respiratory acidosis, the lungs cannot remove enough CO2, leading to its accumulation in the blood. This often occurs in conditions like COPD and is consistent with the patient's smoking history. Metabolic acidosis (choice A) is characterized by low pH and low HCO3 levels. Metabolic alkalosis (choice C) is marked by high pH and high HCO3 levels. Respiratory alkalosis (choice D) presents with high pH and low pCO2.

4. Which of the following is a priority assessment for a client receiving intravenous vancomycin?

• A. Respiratory rate
• B. Blood pressure
• C. Urine output
• D. Hearing acuity

Correct answer: D

Rationale: The correct answer is D, Hearing acuity. Vancomycin is known to cause ototoxicity, which can result in hearing loss. Monitoring the client's hearing acuity is crucial to detect any early signs of ototoxicity. Assessing respiratory rate, blood pressure, and urine output are important assessments in general patient care but are not the priority when specifically monitoring for vancomycin-induced ototoxicity.

5. The parents of a child who has been diagnosed with sickle cell anemia ask why their child experiences pain. What is the most likely cause of the pain?

• A. Inflammation of the vessels
• B. Obstructed blood flow
• C. Overhydration
• D. Stress-related headaches

Correct answer: B

Rationale: The correct answer is B: Obstructed blood flow. In sickle cell anemia, the sickle-shaped red blood cells can clump together, obstructing blood flow in the vessels. This obstruction leads to tissue hypoxia (lack of oxygen) and necrosis, causing pain. Choice A, inflammation of the vessels, is not the primary cause of pain in sickle cell anemia. Choice C, overhydration, is unrelated to the pathophysiology of sickle cell anemia. Choice D, stress-related headaches, is not a characteristic symptom of sickle cell anemia.
