Nursing Elites

1. When considering the concepts related to blood pressure, which statement best describes the concept of mean arterial pressure (MAP)?

• A. MAP is the pressure of the arterial pulse.
• B. MAP reflects the stroke volume of the heart.
• C. MAP is the pressure forcing blood into the tissues, averaged over the cardiac cycle.
• D. MAP is an average of the systolic and diastolic blood pressures and reflects tissue perfusion.

Correct answer: C

Rationale: Mean Arterial Pressure (MAP) is the pressure that forces blood into the tissues, averaged over the cardiac cycle. It is not the pressure of the arterial pulse (Choice A), nor does it directly reflect the stroke volume of the heart (Choice B). While MAP involves systolic and diastolic pressures, it is not simply an average of these two values as diastole lasts longer. Instead, MAP is closer to diastolic pressure plus one third of the pulse pressure. The best description of MAP is that it represents the pressure forcing blood into the tissues, averaged over the cardiac cycle.

2. Which of the following puts the layers of skin in the correct order from right to left?

• A. Dermis, epidermis, hypodermis
• B. Hypodermis, epidermis, dermis
• C. Epidermis, dermis, hypodermis
• D. None of the above

Correct answer: C

Rationale: The correct order of the layers of skin from outermost to innermost is the epidermis, dermis, and then the hypodermis. The epidermis is the outermost layer of the skin, followed by the dermis, which is the middle layer containing connective tissue, hair follicles, and sweat glands. The hypodermis, also known as the subcutaneous tissue, lies beneath the dermis and consists of fat and connective tissue. Choice A is incorrect as it lists the layers in the reverse order. Choice B is incorrect as it reverses the order of the layers. Choice D is incorrect as there is a correct answer among the choices.

3. When assisting a client with shampooing his hair while he is still in bed, a nurse raises the bed to approximately the level of her waist. What is the rationale for this action?

• A. To prevent shampoo from getting into the client's eyes
• B. To allow excess water to run off the edge of the bed
• C. To decrease strain on the nurse's back
• D. To prevent the client's hair from developing tangles

Correct answer: C

Rationale: Raising the bed to the level of the nurse's waist while assisting a client with shampooing in bed is done to reduce strain on the nurse's back. This adjustment ensures that the nurse can work comfortably without excessive bending or stooping, thus preventing back injuries. Choices A, B, and D are incorrect. While preventing shampoo from getting into the client's eyes, allowing excess water to run off the bed, and preventing hair tangles are important considerations, the primary rationale for raising the bed is to prioritize the nurse's ergonomic safety and prevent musculoskeletal strain.

4. For a patient with cirrhosis, which of the following nursing actions can the registered nurse (RN) delegate to unlicensed assistive personnel (UAP)?

• A. Assessing the patient for jaundice
• B. Providing oral hygiene after a meal
• C. Palpating the abdomen for distention
• D. Assisting the patient to choose the diet

Correct answer: B

Rationale: Providing oral hygiene after a meal is an appropriate task to delegate to unlicensed assistive personnel (UAP) as it falls within their scope of practice. UAP can assist with basic personal care activities like oral hygiene. Assessing the patient for jaundice and palpating the abdomen for distention involve making clinical assessments that require a higher level of education and training, typically performed by licensed practical/vocational nurses (LPNs/LVNs) or registered nurses (RNs). Assisting the patient to choose the diet also requires specialized knowledge and would be more appropriate for a nurse to address, considering the complexity of dietary requirements in cirrhosis.

5. You are ready to give your resident a complete bed bath. The temperature of this bath water should be which of the following?

• A. Cooler than a tub bath.
• B. Hotter than a tub bath.
• C. About 106 degrees.
• D. Over 120 degrees.

Correct answer: C

Rationale: The correct temperature for a bed bath water should be about 106 degrees. This temperature is considered safe and comfortable for residents. Using a bath thermometer is essential to ensure the water is not too hot, as hot water can cause burns. On the other hand, water that is too cool can lead to discomfort, shivering, and chilling. Options A, B, and D are incorrect because cooler water may cause discomfort and shivering, hotter water can lead to burns, and water over 120 degrees is considered too hot and risky for a resident's skin.
