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. What is the abbreviation for micro drop?

• A. µgtt
• B. gtt
• C. mdr
• D. mgts

Correct answer: A

Rationale: The correct abbreviation for micro drop is 'µgtt,' where the symbol 'µ' represents micro and 'gtt' stands for drop. Choice B, 'gtt,' is the abbreviation for drop, not specifically for micro drop. Choice C, 'mdr,' and Choice D, 'mgts,' are not standard abbreviations for micro drop and are incorrect.

3. Which of the following actions will most likely lead to a break in the sterile technique for respiratory isolation?

• A. Opening the patient’s window to the outside environment
• B. Turning on the patient’s room ventilator
• C. Opening the door of the patient’s room leading into the hospital corridor
• D. Failing to wear gloves when administering a bed bath

Correct answer: D

Rationale: Failure to wear gloves during a bed bath can potentially introduce pathogens, compromising the sterile technique necessary for respiratory isolation. Proper hand hygiene and personal protective equipment are crucial to prevent the transmission of infectious agents in such settings.

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. What is the appropriate needle size for insulin injection?

• A. 18G, 1 ½” long
• B. 22G, 1” long
• C. 22G, 1 ½” long
• D. 25G, 5/8” long

Correct answer: D

Rationale: The appropriate needle size for insulin injection is 25G, 5/8” long. This size allows for accurate and comfortable insulin administration in subcutaneous tissue.
