1. 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.

2. Which reported symptom would indicate a client with Addison's disease has received too much fludrocortisone (Florinef) replacement?

• A. Oily skin and hair
• B. Weight gain of 6 pounds in one week
• C. Loss of muscle mass in arms and legs
• D. Increased blood glucose level

Correct answer: B

Rationale: Fludrocortisone (Florinef) replacement in Addison's disease involves mimicking aldosterone to retain sodium and water. This retention can lead to weight gain due to increased fluid retention. Rapid weight gain, such as 6 pounds in one week, is a concerning sign of excessive fluid retention, indicating a potential overdose of fludrocortisone. Choices A, C, and D are incorrect because oily skin and hair, loss of muscle mass, and increased blood glucose levels are not specific symptoms of excessive fludrocortisone replacement in Addison's disease.

3. Signs of impaired breathing in infants and children include all of the following except:

• A. nasal flaring
• B. grunting
• C. seesaw breathing
• D. quivering lips

Correct answer: D

Rationale: Signs of impaired breathing in infants and children can manifest in various ways. Nasal flaring, grunting, and seesaw breathing are all indicative of respiratory distress in pediatric patients. Nasal flaring is the widening of the nostrils with breathing effort, grunting is a sound made during exhalation to try to keep the airways open, and seesaw breathing involves the chest moving in the opposite direction of the abdomen. However, quivering lips are not typically associated with impaired breathing in this context. Lip quivering is a distracter and not a common sign of respiratory distress in infants and children. Therefore, the correct answer is 'quivering lips.'

4. A client comes to the clinic for assessment of his physical status and guidelines for starting a weight-reduction diet. The client's weight is 216 pounds and his height is 66 inches. The nurse identifies the BMI (body mass index) as:

• A. within normal limits, so a weight-reduction diet is unnecessary
• B. lower than normal, so education about nutrient-dense foods is needed
• C. indicating obesity because the BMI is 35
• D. indicating overweight status because the BMI is 27

Correct answer: C

Rationale: Obesity is defined by a BMI of 30 or more with no co-morbid conditions. It is calculated by utilizing a chart or nomogram that plots height and weight. This client's BMI is 35, indicating obesity. Choices A, B, and D are incorrect because the client's BMI is above 30, which falls under the obesity category. Therefore, a weight-reduction diet and increased physical activity are necessary to address the client's weight status and promote overall health.

5. Which of the following injuries, presented by a client entering the Emergency Department, is the highest priority?

• A. open leg fracture
• B. open head injury
• C. stab wound to the chest
• D. traumatic amputation of a thumb

Correct answer: C

Rationale: A stab wound to the chest is the highest priority injury. This type of injury can lead to lung collapse and mediastinal shift, potentially resulting in death if left untreated. Treating an obstructed airway or a chest wound takes precedence over addressing hemorrhage. The principle of ABC (airway, breathing, and circulation) guides care decisions in prioritizing life-threatening situations. An open leg fracture, open head injury, and traumatic amputation of a thumb, while serious, do not pose an immediate threat to life compared to a stab wound to the chest. An open leg fracture may lead to significant blood loss but is not immediately life-threatening. An open head injury requires assessment and intervention but does not impact airway, breathing, or circulation directly. Traumatic amputation of a thumb is a serious injury but can be managed after addressing more life-threatening conditions.
