Nursing Elites

1. Which of the following blood tests should be performed before a blood transfusion?

• A. Prothrombin and coagulation time
• B. Blood typing and cross-matching
• C. Bleeding and clotting time
• D. Complete blood count (CBC) and electrolyte levels

Correct answer: B

Rationale: Before administering a blood transfusion, it is crucial to perform blood typing and cross-matching to ensure compatibility between the donor's blood and the recipient's blood. This process helps prevent adverse reactions such as transfusion reactions, which can be life-threatening. Prothrombin and coagulation time, bleeding and clotting time, as well as CBC and electrolyte levels are important tests in other clinical contexts, but for blood transfusions, blood typing and cross-matching are essential to ensure patient safety.

2. A nurse obtained a client’s pulse and found the rate to be above normal. The nurse documents this finding as:

• A. Tachypnea
• B. Hyperpyrexia
• C. Arrhythmia
• D. Tachycardia

Correct answer: D

Rationale: When a nurse finds a client's pulse rate to be above normal, it is documented as tachycardia. Tachycardia specifically refers to an elevated heart rate, while tachypnea is rapid breathing, hyperpyrexia is high fever, and arrhythmia is an irregular heartbeat. Therefore, the correct term to describe an above-normal pulse rate is tachycardia.

3. A client is to receive thrombolytic therapy. Which of the following factors should be recognized as a contraindication to the therapy?

• A. Hip arthroplasty 2 weeks ago
• B. Elevated sedimentation rate
• C. Incident of exercise-induced asthma 1 week ago
• D. Elevated platelet count

Correct answer: A

Rationale: Thrombolytic therapy involves the use of medications to dissolve blood clots. Hip arthroplasty (joint replacement surgery) performed recently is a contraindication to thrombolytic therapy due to the risk of bleeding. Elevated sedimentation rate, exercise-induced asthma, and elevated platelet count are not contraindications to thrombolytic therapy.

4. The client was asked to read the Snellen chart. Which of the following is being tested?

• A. Optic
• B. Olfactory
• C. Oculomotor
• D. Trochlear

Correct answer: A

Rationale: The correct answer is A: Optic. The Snellen chart is used to test visual acuity, which assesses the function of the optic nerve responsible for vision. Choices B, C, and D are incorrect. Olfactory relates to the sense of smell, oculomotor controls eye movement, and trochlear controls certain eye muscles. Therefore, the only option related to vision testing in this context is the optic nerve.

5. The physician orders 10 gr of aspirin for a patient. The equivalent dose in milligrams is:

• A. 0.6 mg
• B. 10 mg
• C. 60 mg
• D. 600 mg

Correct answer: D

Rationale: To convert grains (gr) to milligrams (mg), you multiply by 60. Therefore, 10 gr of aspirin is equal to 600 mg (10 gr x 60 = 600 mg). So, the correct answer is 600 mg.
