1. Diabetes insipidus is the result of:

A. A diet high in sugar and carbohydrates.
B. A complicated pregnancy.
C. A disorder of the pancreas.
D. A disorder of the pituitary gland.

Correct answer: D

Rationale: Diabetes insipidus is caused by a disorder of the pituitary gland affecting ADH regulation. This disorder results in the decreased production or release of antidiuretic hormone (ADH), leading to the inability of the kidneys to concentrate urine properly. Choices A, B, and C are incorrect as they do not relate to the underlying cause of diabetes insipidus.

2. A nurse reviews the electrolyte results of an assigned client and notes that the potassium level is 5.4 mEq/L. Which of the following would the nurse expect to note on the electrocardiogram as a result of the laboratory value?

A. ST depression
B. Inverted T wave
C. Prominent U wave
D. Tall peaked T waves

Correct answer: D

Rationale: The correct answer is 'Tall peaked T waves.' Tall peaked T waves are characteristic ECG changes associated with hyperkalemia. In hyperkalemia, the elevated potassium levels affect the myocardium, leading to changes in the ECG. ST depression (Choice A) is more commonly associated with myocardial ischemia or infarction. Inverted T wave (Choice B) is seen in conditions like myocardial ischemia or CNS events. Prominent U wave (Choice C) is typically associated with hypokalemia or certain medications. Therefore, in this scenario, the nurse would expect to note tall peaked T waves on the electrocardiogram due to the elevated potassium level.

3. Which preventive measure can be employed to decrease the risk of compartment syndrome?

A. The administration of a potassium-sparing diuretic for heart failure
B. A bivalve cast for a skeletal fracture
C. A cerebral diuretic to decrease intracranial pressure after a head injury
D. A chest tube to restore normal intrathoracic pressure after a pneumothorax

Correct answer: B

Rationale: The correct answer is B. A bivalve cast can help decrease the risk of compartment syndrome by providing space for swelling, thus preventing the build-up of pressure within the muscles. Choices A, C, and D are incorrect because they are not directly related to preventing compartment syndrome. Choice A is more focused on managing heart failure, choice C on reducing intracranial pressure, and choice D on restoring intrathoracic pressure after a pneumothorax, which are not relevant to preventing compartment syndrome.

4. Which patient is exercising their right to autonomy in the context of patient rights?

A. An 86-year-old female who remains independent in terms of the activities of daily living.
B. An unemancipated 16-year-old who chooses to not have an intravenous line.
C. A 32-year-old who does not need the help of the nurse to bathe and groom themselves.
D. A 99-year-old who wants CPR despite the fact that the nurse and doctor do not think that it would be successful.

Correct answer: D

Rationale: The correct answer is D. A 99-year-old exercising their right to autonomy in the context of patient rights by choosing CPR. Autonomy in healthcare refers to the patient's right to make their own decisions about their care, even if healthcare providers may disagree. In this scenario, the 99-year-old patient is exercising autonomy by making an informed choice about their medical treatment, despite healthcare professionals having a different opinion. Choices A, B, and C do not directly demonstrate the exercise of autonomy in decision-making regarding medical treatment, making them incorrect.

5. Which individual is most at risk for Osgood-Schlatter disease?

A. An elderly female who is hospitalized with a hip fracture and on bed rest
B. A middle-aged male patient who has been exposed to asbestos in the shipping industry
C. An adolescent who is physically active and the captain of their soccer team
D. An infant of low birth weight and a gestational age of 28 weeks

Correct answer: C

Rationale: Osgood-Schlatter disease is a condition that commonly affects adolescents who are physically active, especially during growth spurts. It is caused by overuse of the knee, leading to inflammation of the patellar ligament at the tibial tuberosity. The repetitive stress on the growth plate during activities like running and jumping can trigger this condition. Therefore, an adolescent who is physically active and the captain of their soccer team is most at risk for Osgood-Schlatter disease. Choices A, B, and D are not at high risk for this condition as it is primarily seen in active adolescents.
