Nursing Elites

1. In reviewing the assessment data of a client suspected of having diabetes insipidus, the nurse expects which of the following after a water deprivation test?

• A. Increased edema and weight gain
• B. Unchanged urine specific gravity
• C. Rapid protein excretion
• D. Decreased blood potassium

Correct answer: B

Rationale: After a water deprivation test in a client suspected of having diabetes insipidus, the nurse would expect the urine specific gravity to remain unchanged. This occurs because in diabetes insipidus, the kidneys are unable to concentrate urine, leading to a low urine specific gravity even after water deprivation. Choices A, C, and D are incorrect. Increased edema and weight gain are not typical findings in diabetes insipidus. Rapid protein excretion is not directly related to the condition, and decreased blood potassium is not a common outcome of a water deprivation test for diabetes insipidus.

2. A 16-month-old child has just been admitted to the hospital. As the nurse assigned to this child enters the hospital room for the first time, the toddler runs to the mother, clings to her, and begins to cry. What would be the initial action by the nurse?

• A. Arrange for a change in client care assignments
• B. Explain that this behavior is expected
• C. Discuss the appropriate use of 'time-out'
• D. Explain that the child is in need of extra attention

Correct answer: B

Rationale: The correct answer is to explain that this behavior is expected. At 16 months of age, children commonly experience separation anxiety, especially in unfamiliar environments like hospitals. It is important for the nurse to reassure the child and the parent that such behavior is normal. Option A is incorrect as there is no need to change client care assignments based on the child's behavior. Option C is not appropriate as discussing the use of 'time-out' is more relevant in behavior management for older children. Option D is incorrect as it does not address the underlying cause of the child's behavior related to separation anxiety.

3. A client is admitted with a diagnosis of myocardial infarction (MI). The client is complaining of chest pain. The nurse knows that pain related to an MI is due to

• A. Insufficient oxygenation of the cardiac muscle
• B. Potential circulatory overload
• C. Left ventricular overload
• D. Electrolyte imbalance

Correct answer: A

Rationale: The correct answer is A: Insufficient oxygenation of the cardiac muscle. Myocardial infarction pain is primarily caused by inadequate oxygen reaching the heart muscle, leading to ischemia and tissue damage. Choices B, C, and D are incorrect because circulatory overload, left ventricular overload, and electrolyte imbalance are not the primary causes of chest pain in myocardial infarction. Circulatory overload may lead to other symptoms like edema, left ventricular overload can result in heart failure symptoms, and electrolyte imbalance may present with various manifestations, but none of these directly cause the characteristic chest pain associated with an MI.

4. An activity designed to diagnose and treat a disease or condition in its earliest stages, before it becomes full-blown, would be classified as:

• A. primary prevention
• B. secondary prevention
• C. tertiary prevention
• D. health education

Correct answer: B

Rationale: The correct answer is B, secondary prevention. Secondary prevention focuses on early diagnosis and intervention to prevent the progression of a disease or condition. This involves detecting and treating the illness in its early stages to reduce its impact. Choice A, primary prevention, aims to prevent the development of a disease or injury before it occurs by promoting healthy behaviors. Choice C, tertiary prevention, involves managing and improving the quality of life of individuals with established conditions to prevent complications and further deterioration. Choice D, health education, refers to providing information and promoting awareness about health issues to enable individuals to make informed decisions and adopt healthy behaviors.

5. Postoperative orders for a client undergoing a mitral valve replacement include monitoring pulmonary artery pressure together with pulmonary capillary wedge pressure with a pulmonary artery catheter. This action by the nurse will assess

• A. Right ventricular pressure
• B. Left ventricular end-diastolic pressure
• C. Acid-Base balance
• D. Coronary artery stability

Correct answer: B

Rationale: The correct answer is B: Left ventricular end-diastolic pressure. Pulmonary capillary wedge pressure is used to assess left ventricular end-diastolic pressure. This measurement provides valuable information on the filling pressure of the left ventricle. Choices A, C, and D are incorrect because monitoring pulmonary capillary wedge pressure does not directly assess right ventricular pressure, acid-base balance, or coronary artery stability.
