Nursing Elites

1. If a patient's blood pressure is 150/96, what is his pulse pressure?

• A. 54
• B. 96
• C. 150
• D. 246

Correct answer: A

Rationale: Pulse pressure is calculated by subtracting the diastolic pressure from the systolic pressure. In this case, the systolic pressure is 150 and the diastolic pressure is 96. Therefore, the pulse pressure is 150 - 96 = 54. Pulse pressure represents the force generated by the heart with each contraction and is an important indicator of cardiovascular health.

2. When is the most appropriate time for obtaining a sputum specimen for culture?

• A. Early in the morning
• B. After the patient eats a light breakfast
• C. After aerosol therapy
• D. After chest physiotherapy

Correct answer: A

Rationale: Obtaining a sputum specimen early in the morning is the most appropriate time because secretions have accumulated overnight. This timing provides the best sample with the least contamination, leading to more accurate culture results and aiding in diagnosing respiratory infections effectively.

3. A client has diaper dermatitis. Which of the following actions should the nurse take?

• A. Apply zinc oxide ointment to the irritated area.
• B. Wipe stool from the skin using store-bought baby wipes.
• C. Apply talcum powder to the irritated area.
• D. None of the above

Correct answer: A

Rationale: Diaper dermatitis, also known as diaper rash, is a common condition in babies or clients who wear diapers. The primary intervention for diaper dermatitis is to apply a protective barrier cream, such as zinc oxide ointment, to the irritated area. This helps to protect the skin from irritants and promotes healing. Wiping stool from the skin using baby wipes may further irritate the skin, and talcum powder is no longer recommended due to potential respiratory risks when inhaled. Therefore, the correct action for the nurse in this scenario is to apply zinc oxide ointment to the irritated area.

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 conditions may necessitate fluid restriction?

• A. Fever
• B. Chronic Obstructive Pulmonary Disease
• C. Renal Failure
• D. Dehydration

Correct answer: C

Rationale: Renal failure often necessitates fluid restriction to prevent fluid overload. In renal failure, the kidneys are unable to effectively filter and excrete excess fluids, leading to fluid accumulation in the body. Restricting fluid intake helps manage this condition by preventing further fluid buildup and complications such as edema and electrolyte imbalances.
