1. An adult's blood pressure reads 40/20. You place the patient in a Trendelenberg position before rechecking the blood pressure. What actions will you take to position the patient correctly?
- A. lower the head of the bed and raise the foot of the bed
- B. raise the head of the bed up to about 60 to 75 degrees
- C. raise the head of the bed up to about 75 to 90 degrees
- D. raise the siderails and place the bed in the high position
Correct answer: A
Rationale: In a Trendelenberg position, used for low blood pressure, the correct action is to lower the head of the bed and raise the foot of the bed. This positioning facilitates the return of blood to the heart and helps increase blood pressure. Option B, raising the head of the bed to 60 to 75 degrees, is incorrect as it is not the Trendelenberg position. Option C, raising the head of the bed to 75 to 90 degrees, is incorrect as it does not align with the Trendelenberg position. Option D, raising the siderails and placing the bed in the high position, is incorrect as it does not address the specific positioning required for the Trendelenberg position.
2. In the Gram Stain procedure, which component acts as the mordant?
- A. Crystal violet
- B. Methyl alcohol
- C. Iodine
- D. Safranin
Correct answer: C
Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.
3. To properly read a meniscus,
- A. hold the measuring device at eye level and read the bottom of the curve of the liquid level
- B. hold the measuring device at eye level and read the top of the curve of the liquid level where the liquid adheres to the walls of the container.
- C. hold the measuring device at table level and, looking down into the measuring device, read the bottom of the curve of the liquid level.
- D. hold the measuring device at table level and, looking down into the measuring device, read the top of the curve of the liquid level.
Correct answer: A
Rationale: To properly read a meniscus, it is essential to hold the measuring device at eye level to avoid parallax error. Reading the bottom of the curve of the liquid level is correct because the meniscus is the concave or convex curve at the liquid's surface. Choice B is incorrect because reading the top of the curve where the liquid adheres to the walls of the container can lead to inaccurate measurements. Choices C and D are incorrect as they suggest holding the device at table level, which can introduce parallax error and result in an incorrect reading.
4. How does the procedure for taking a pulse rate on an infant differ from an adult?
- A. Pulse rates are taken on infants using a different method.
- B. The apical pulse method is used on infants.
- C. Pulse rates on infants are taken with a sphygmomanometer.
- D. Pulse rates on infants are taken apically in the third intercostal space.
Correct answer: B
Rationale: The correct answer is B: The apical pulse method is used on infants. This method involves placing a stethoscope in the fifth intercostal space, mid-clavicular line, and counting the beats for a full minute. It is a preferred method for infants due to their small size and the difficulty in palpating peripheral pulses accurately. Choices A, C, and D are incorrect. Choice A is incorrect as pulse rates are indeed taken on infants, albeit using a different method. Choice C is incorrect as a sphygmomanometer is typically used for measuring blood pressure, not pulse rates. Choice D is incorrect as pulse rates on infants are usually taken apically in the fifth intercostal space, not the third.
5. The hospital has sounded the call for a disaster drill on the evening shift. Which of these clients would the nurse prioritize first on the list to be discharged in order to make a room available for a new admission?
- A. A middle-aged client with a history of being ventilator dependent for over seven (7) years and admitted with bacterial pneumonia five days ago.
- B. A young adult with diabetes mellitus Type 2 for over ten (10) years and admitted with antibiotic-induced diarrhea 24 hours ago.
- C. An elderly client with a history of hypertension, hypercholesterolemia, and lupus, and was admitted with Stevens-Johnson syndrome that morning.
- D. An adolescent with a positive HIV test and admitted for acute cellulitis of the lower leg 48 hours ago.
Correct answer: A
Rationale: The best candidate for discharge during a need for emergency room availability is a stable patient with a chronic condition who is familiar with their care. In this scenario, the middle-aged client in option A, who has been ventilator dependent for over seven years and admitted with bacterial pneumonia five days ago, is most suitable for discharge. This client is likely stable and can continue medication therapy at home, making them the most appropriate choice for discharge at this time. Choice B should not be the priority for discharge as the young adult with diabetes mellitus Type 2 admitted with antibiotic-induced diarrhea 24 hours ago may need further monitoring and management of their condition. Choice C, the elderly client with multiple comorbidities and admitted with Stevens-Johnson syndrome on the same day, is not a suitable candidate for immediate discharge as they may require ongoing medical attention and observation. Choice D, the adolescent with a positive HIV test and admitted for acute cellulitis of the lower leg 48 hours ago, should not be discharged first as acute cellulitis may require continued treatment and monitoring, especially in the context of a positive HIV status.
