Nursing Elites

1. The healthcare provider is examining a patient who is reporting "feeling cold."? Which is a mechanism of heat loss in the body?

• A. Exercise
• B. Radiation
• C. Metabolism
• D. Food digestion

Correct answer: B

Rationale: When the body needs to lose heat, one of the mechanisms it employs is radiation. Radiation involves the transfer of heat from the body to the environment in the form of infrared waves. While metabolism, exercise, and food digestion contribute to heat production, they are not mechanisms for heat loss. Metabolism generates heat as a byproduct, exercise increases metabolic rate leading to heat production, and food digestion involves some heat generation, but these processes do not directly facilitate heat loss. Therefore, in the scenario where the patient is feeling cold, radiation is the primary mechanism for the body to lose excess heat and maintain a stable internal temperature.

2. Mr. Thomas is a well-groomed 68-year-old male patient who had prostate surgery two days ago. He has an indwelling catheter and a urinary drainage bag. You have weighed him at 9 am each morning for 3 mornings in a row. Today, on the 4th day, his morning weight is 3 pounds more than it was the day before. Why could he have gained these 3 pounds in one day, on a 1000 calorie diet?

• A. It is obvious that his visitors have been sneaking him junk food from the local fast-food restaurant.
• B. It may be that his urinary drainage bag was not emptied today and it was emptied on previous days.
• C. It is obvious that the scale is broken and it should be replaced immediately to prevent these false weights.
• D. A 3-pound weight gain is not significant enough to question and should just be noted.

Correct answer: B

Rationale: The correct answer is that the weight gain may be due to the urinary drainage bag not being emptied today, while it was emptied on previous days. This scenario is common and can lead to an increase in weight that is not related to food intake. Choice A is incorrect because assuming visitors are sneaking junk food is speculative and not based on facts. Choice C is incorrect as there is no evidence to suggest the scale is broken. Choice D is incorrect because any unexplained weight gain should be investigated further, even if it seems insignificant at first.

3. What is a common error when taking a pulse?

• A. Placing the index finger on the radial artery located on the thumb side of a patient's wrist.
• B. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure.
• C. Counting the pulse for 15 seconds and multiplying the number by four.
• D. None of the above will cause errors.

Correct answer: C

Rationale: The correct answer is counting the pulse for 15 seconds and multiplying the number by four. To accurately assess a patient's heart rate or pulse, it is crucial to count the pulse for a full minute. Counting for only 15 seconds and then multiplying by four may result in an inaccurate heart rate calculation. This approach could miss arrhythmias or intermittent pulsations that could be vital indicators of the patient's condition. Placing the index finger on the radial artery, which is located on the thumb side of the patient's wrist, is the correct technique for taking a pulse. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure is a valid observation and not an error in itself. Therefore, the most common error in this scenario is incorrectly calculating the pulse rate by multiplying a 15-second count by four.

4. When assessing the force or strength of a pulse, what would the nurse recall about the pulse?

• A. Is a reflection of the heart's stroke volume
• B. Typically recorded on a 0- to 3-point scale
• C. Demonstrates elasticity of the blood vessel wall
• D. Reflects the blood volume in the arteries during diastole

Correct answer: A

Rationale: When assessing the force or strength of a pulse, the nurse should recall that it is a reflection of the heart's stroke volume. The heart pumps an amount of blood (the stroke volume) into the aorta, causing arterial walls to flare and generate a pressure wave felt as the pulse in the periphery. The force of the pulse is typically recorded on a 0- to 3-point scale, not a 0- to 2-point scale. The force of the pulse does not demonstrate the elasticity of blood vessel walls or reflect the blood volume in the arteries during diastole. Therefore, choices B, C, and D are incorrect.

5. A nurse is preparing to change a client's dressing for a burn wound on his foot. Which of the following interventions is appropriate for this process?

• A. Wash the wound with cleanser, rinse, and pat dry
• B. Bind the wound tightly, secure with tape, and elevate the foot
• C. Contact the physician after the dressing change is complete
• D. Provide analgesics for the client after the procedure

Correct answer: A

Rationale: When changing the dressing for a burn wound, it is essential to follow appropriate interventions to prevent infection, reduce pain, and support healing. In this scenario, after removing the old dressing, it is crucial to wash the wound gently with a suitable cleanser, rinse the area thoroughly, and then pat it dry. This process helps in maintaining cleanliness, reducing the risk of infection, and providing a conducive environment for healing. Binding the wound tightly (Choice B) can impede circulation and delay healing. Contacting the physician after the dressing change (Choice C) may be necessary in specific situations but is not a standard step in routine dressing changes. Providing analgesics after the procedure (Choice D) is important for pain management but is not directly related to the dressing change itself.
