Nursing Elites

1. When educating a client about their new prescription for warfarin, what should the nurse advise?

• A. To have his white blood cell count tested once a month
• B. To avoid any activities that could lead to injury
• C. To avoid eating leafy green vegetables
• D. Both A and B

Correct answer: B

Rationale: The correct answer is to advise the client to avoid any activities that could lead to injury when taking warfarin. Warfarin is an anticoagulant medication that decreases blood clotting, increasing the risk of bleeding. Engaging in activities that may result in injury can lead to uncontrolled bleeding, which can be serious. While monitoring white blood cell count is not specifically related to warfarin therapy, avoiding leafy green vegetables is important due to their vitamin K content, which can interfere with warfarin's effectiveness. Therefore, the client should be educated to avoid activities that could cause injury to prevent potential bleeding complications.

2. To accurately assess a patient's respiration rate, which of the following methods would be BEST?

• A. Tell the patient, 'Please remain silent while I count your number of breaths.'
• B. Count respirations at the same time you are counting the pulse rate
• C. Count the pulse rate for one minute, then, while keeping your index fingers on the patient's radial artery, count the respirations for an additional minute.
• D. Count the patient's respiration rate, then take the patient's temperature, and then take the pulse rate.

Correct answer: B

Rationale: The most accurate method to assess a patient's respiration rate is to count the breaths simultaneously while counting the pulse rate. This approach ensures that the patient is unaware of the specific focus on their breathing, preventing any conscious alteration in breathing patterns. Choice A is incorrect because informing the patient may lead to altered breathing as the patient may consciously change their breathing pattern. Choice C involves counting the pulse rate first, which is not necessary for assessing respiration rate. Choice D is incorrect as it includes unnecessary steps such as taking the patient's temperature before counting respiration rate, which adds no value to accurately assessing the respiration rate.

3. Where is the Loop of Henle located in the body?

• A. Liver
• B. Kidney
• C. Heart
• D. Ear

Correct answer: B

Rationale: The Loop of Henle is a crucial structure found in the kidneys. It plays a vital role in the concentration of urine by creating a concentration gradient in the renal medulla. Choices A, C, and D are incorrect because the Loop of Henle is not located in the liver, heart, or ear. Understanding the anatomical location of the Loop of Henle is essential in comprehending renal physiology and the mechanism of action of diuretic medications.

4. When assessing a 75-year-old patient who has asthma, the nurse notes that the patient assumes a tripod position, leaning forward with arms braced on the chair. How would the nurse interpret these findings?

• A. Interpret that the patient is eager and interested in participating in the interview.
• B. Evaluate the patient for abdominal pain, which may be exacerbated in the sitting position.
• C. Interpret that the patient is having difficulty breathing and assist them to a supine position.
• D. Recognize that a tripod position is often used when a patient is having respiratory difficulties.

Correct answer: D

Rationale: Assuming a tripod position"?leaning forward with arms braced on chair arms"?occurs with chronic pulmonary diseases like asthma. This position helps improve breathing by allowing better use of respiratory muscles. Option A is incorrect because assuming the tripod position is not related to being eager or interested in participating in an interview. Option B is incorrect as abdominal pain is not typically associated with the tripod position in this context. Option C is incorrect as assisting the patient to a supine position would not address the underlying respiratory difficulty indicated by the tripod position. Therefore, the correct interpretation is to recognize that the patient is likely experiencing respiratory difficulties when assuming the tripod position.

5. Which of the following statements best describes substance P?

• A. Substance P decreases a client's sensitivity to pain
• B. Substance P levels are drawn before administration of narcotic analgesics
• C. Substance P is found in the brain and is responsible for pain control and management of depression
• D. Substance P is found in the dorsal horn of the spinal column

Correct answer: D

Rationale: Substance P is a neurotransmitter found in the brain and the dorsal horn of the spinal column, not just in the brain. It is associated with pain transmission and modulation. Substance P is known to cause inflammation, edema, and pain. While it plays a role in pain perception, it does not decrease a client's sensitivity to pain (Choice A), nor are its levels typically drawn before administering narcotic analgesics (Choice B). Although substance P is involved in pain control, it is not responsible for managing depression (Choice C). Therefore, the correct statement is that substance P is found in the dorsal horn of the spinal column.
