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 client is being cared for by a nurse 2 hours after admission. The client has an SaO2 of 91%, exhibits audible wheezes, and is using accessory muscles when breathing. Which of the following classes of medication should the nurse expect to administer?

• A. Antibiotic
• B. Beta-blocker
• C. Antiviral
• D. Beta2 agonist

Correct answer: D

Rationale: The client's presentation with an SaO2 of 91%, audible wheezes, and use of accessory muscles indicates respiratory distress, likely due to bronchoconstriction. Beta2 agonists are the appropriate class of medications to administer in this situation as they act as bronchodilators, helping to relieve the bronchoconstriction and improve airflow to the lungs. Antibiotics, beta-blockers, and antivirals are not indicated for this client's respiratory distress symptoms.

3. How many drops are equivalent to 1 tsp?

• A. 15
• B. 60
• C. 10
• D. 30

Correct answer: B

Rationale: 1 teaspoon (tsp) is equivalent to approximately 60 drops. Drops and teaspoons vary in volume and size, affecting the conversion ratio. Choice A (15 drops) is incorrect as it's a common misconception. Choice C (10 drops) and Choice D (30 drops) do not align with the standard conversion of 1 tsp to 60 drops.

4. Which of the following is not a cause of tachycardia?

• A. Fever
• B. Exercise
• C. Sympathetic nervous system stimulation
• D. Parasympathetic nervous system stimulation

Correct answer: D

Rationale: Tachycardia is an increased heart rate, and it can be caused by various factors such as fever, exercise, and sympathetic nervous system stimulation, all of which tend to increase heart rate. However, parasympathetic nervous system stimulation typically slows the heart rate, making it the exception among the choices provided. Thus, parasympathetic nervous system stimulation is not a cause of tachycardia.

5. Which of the following scenarios represents nursing malpractice?

• A. The nurse administers penicillin to a patient with a documented history of allergy to the drug. The patient experiences an allergic reaction and suffers cerebral damage due to anoxia.
• B. The nurse applies a hot water bottle or a heating pad to the abdomen of a patient with abdominal cramping.
• C. The nurse assists a patient out of bed with the bed locked in position; the patient slips and fractures his right humerus.
• D. The nurse administers the wrong medication to a patient, resulting in vomiting. This error is documented and reported to the physician and the nursing supervisor.

Correct answer: A

Rationale: The correct answer is A. Administering a drug to a patient with a known allergy, leading to severe harm such as an allergic reaction causing cerebral damage due to anoxia, constitutes nursing malpractice. In this scenario, the nurse failed to adhere to the standard of care by administering a medication that the patient was allergic to, resulting in serious harm, which is a clear example of malpractice in nursing.
