1. The community health nurse is performing a home visit to an 84-year-old woman recovering from hip surgery. The nurse notes that the woman seems uncharacteristically confused and has dry mucous membranes. When asked about her fluid intake, the patient states, I stop drinking water early in the day because it is just too difficult to get up during the night to go to the bathroom. What would be the nurses best response?

A. I will need to have your medications adjusted so you will need to be readmitted to the hospital for a complete workup
B. Limiting your fluids can create imbalances in your body that can result in confusion. Maybe we need to adjust the timing of your fluids.
C. It is normal to be a little confused following surgery, and it is safe not to urinate at night.
D. If you build up too much urine in your bladder, it can cause you to get confused, especially when your body is under stress.

Correct answer: B

Rationale:

2. After administering 40 mEq of potassium chloride, a nurse evaluates the clients response. Which manifestations indicate that treatment is improving the clients hypokalemia? (Select all tha do not t apply.)

A. Strong productive cough
B. Active bowel sounds
C. U waves present on the electrocardiogram (ECG)
D.

Correct answer: C

Rationale:

3. The term used to describe a blood sodium level of more than 145 mEq/L is:

A. hyponatremia.
B. hyperkalemia.
C. hypernatremia.
D. hypercalcemia.

Correct answer: C

Rationale: The correct answer is C: hypernatremia. Hypernatremia refers to an elevated level of sodium in the blood, specifically when it is more than 145 mEq/L. Choice A, hyponatremia, is incorrect as it refers to low sodium levels. Choice B, hyperkalemia, is incorrect as it refers to high potassium levels, not sodium. Choice D, hypercalcemia, is also incorrect as it relates to elevated calcium levels, not sodium.

4. What is the fluid that surrounds the cells called?

A. plasma
B. interstitial fluid
C. intracellular fluid
D. edema

Correct answer: B

Rationale: The correct answer is interstitial fluid. Interstitial fluid is the fluid that surrounds and fills the spaces between cells, facilitating nutrient and waste exchange. Plasma, referred to in choice A, is the liquid part of blood. Choice C, intracellular fluid, is the fluid inside cells. Choice D, edema, is an abnormal accumulation of fluid in interstitial spaces, causing swelling.

5. A patient with diabetes insipidus is admitted to the intensive care unit after a motor vehicle accident that resulted in head trauma and damage to the pituitary gland. Diabetes insipidus can occur when there is a decreased production of which of the following?

A. ADH
B. Estrogen
C. Aldosterone
D. Renin

Correct answer: A

Rationale: The correct answer is A: ADH. Diabetes insipidus is characterized by a deficiency in antidiuretic hormone (ADH), leading to excessive urine output and thirst. In this scenario, the head trauma and damage to the pituitary gland can result in decreased production or release of ADH. Estrogen (Choice B) is not directly related to diabetes insipidus. Aldosterone (Choice C) is a hormone that regulates sodium and potassium levels, not water balance like ADH. Renin (Choice D) is an enzyme involved in the regulation of blood pressure and fluid balance but not directly related to diabetes insipidus.
