1. The client asked about the role of leptin in the body. Which response should the nurse provide?
- A. It increases food intake in clients, thereby promoting obesity.
- B. It assists in the regulation of steroids.
- C. It increases the total fat mass of people who are obese.
- D. It might decrease the total fat mass in the bodies of people who are obese.
Correct answer: D
Rationale: Leptin is a protein hormone expressed in fat cells that regulates fat cell percentage in the body. It is associated with increased energy expenditure and decreased food intake through hypothalamic control. In obese individuals, there may be insensitivity or resistance to leptin's effects. Leptin influences other hormones like insulin and genetic factors related to fat regulation. Therefore, the correct response is that leptin might decrease total fat mass in obese individuals as it is involved in energy balance and fat regulation. Choices A, B, and C are incorrect because leptin does not increase food intake or promote obesity; it does not assist in the regulation of steroids, and it does not increase total fat mass in people who are obese.
2. The client is cared for by a nurse and calls for the nurse to come to the room, expressing feeling unwell. The client's vital signs are BP: 130/88, HR: 102, RR: 28. What should the nurse do next?
- A. Administer PRN anxiolytic
- B. Administer Antibiotics
- C. Reassure the client that everything is okay and offer food and beverage
- D. Determine the Glasgow Coma Scale
Correct answer: A
Rationale: Correct! The client's vital signs indicate tachycardia and tachypnea, which could be indicative of hypoxia. Administering a PRN anxiolytic would not address the underlying issue and could mask deterioration. Reassuring the client without further assessment or intervention could lead to a delay in appropriate care if there is a serious underlying cause for the symptoms. Determining the Glasgow Coma Scale is not relevant to the client's presenting symptoms of feeling unwell and suspecting something is wrong, coupled with abnormal vital signs.
3. The client is undergoing progressive ambulation on the third day after a myocardial infarction. Which clinical manifestation would indicate that the client should not be advanced to the next level?
- A. Facial flushing
- B. A complaint of chest heaviness
- C. Heart rate increase of 10 beats/min
- D. Systolic blood pressure increase of 10 mm Hg
Correct answer: B
Rationale: The correct answer is a complaint of chest heaviness. Onset of chest pain indicates myocardial ischemia, which can be life-threatening. Chest pain in a client post-myocardial infarction should be promptly evaluated, and the activity level should not be advanced. Choices A, C, and D are not the best options because facial flushing, a heart rate increase of 10 beats/min, and a systolic blood pressure increase of 10 mm Hg are not typical indicators of myocardial ischemia or necessarily contraindications for advancing activity levels in this context.
4. A client, age 28, was recently diagnosed with Hodgkin's disease. After staging, therapy is planned to include combination radiation therapy and systemic chemotherapy with MOPP"?nitrogen mustard, vincristine (Onconvin), prednisone, and procarbazine. In planning care for this client, the nurse should anticipate which of the following side effects to contribute to a sense of altered body image?
- A. Cushingoid appearance
- B. Alopecia
- C. Temporary or permanent sterility
- D. Pathologic fractures
Correct answer: B
Rationale: The correct answer is B: alopecia. Chemotherapy drugs like vincristine and nitrogen mustard commonly cause hair loss (alopecia), which can significantly impact body image. While a Cushingoid appearance can be a side effect of long-term steroid use, it is not typically associated with the chemotherapy regimen mentioned. Temporary or permanent sterility can result from chemotherapy, affecting fertility but not directly contributing to altered body image. Pathologic fractures are not commonly linked to Hodgkin's disease or its treatment, unlike alopecia which is a well-known side effect.
5. What is the most common cause of acute renal failure?
- A. Shock
- B. Nephrotoxic drugs
- C. Enlarged prostate
- D. Diabetes
Correct answer: A
Rationale: The most common cause of acute renal failure is shock. In cases of shock, such as hypovolemic shock where there is low blood volume, the kidneys receive inadequate blood flow leading to acute renal failure. This can result in the kidneys starting to die within 20 minutes of low pressure. While nephrotoxic drugs can also cause acute renal failure, shock is more commonly associated with this condition. An enlarged prostate can lead to urinary retention but is not the most common cause of acute renal failure. Diabetes, on the other hand, can cause chronic kidney disease over time but is not typically the primary cause of acute renal failure.
