Question 1 of 9
The nurse is evaluating a patient's laboratory results. Based upon the laboratory findings, what results will cause the release of an antidiuretic hormone (ADH)?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 9
The nurse is caring for a postthyroidectomy patient at risk for hypocalcemia. What action should the nurse take when assessing for hypocalcemia?
Correct Answer: D
Rationale: Muscle twitching and numbness or tingling of the lips, fingers, and toes are signs of hyperirritability of the nervous system due to hypocalcemia. The other options describe complications the nurse should also be observing for; however, tetany and neurologic alterations are primary indications of hypocalcemia.
Question 3 of 9
A patient admitted with a gastrointestinal bleed and anemia is receiving a blood transfusion. Based upon the patient's hypotensive blood pressure, the nurse anticipates an order for IV fluids from the physician. Which of the following IV solutions may be administered with blood products?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 9
A patient is in the hospital with heart failure. The nurse notes during the evening assessment that the patient's neck veins are distended and the patient has dyspnea. What action should the nurse take?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 9
A nurse in the medical-surgical unit is giving a patient with low blood pressure a hypertonic solution, which will increase the number of dissolved particles in his blood, creating pressure for fluids in the tissues to shift into the capillaries and increase the blood volume. Which of the following terms is associated with this process?
Correct Answer: B
Rationale: Osmosis is the movement of fluid from a region of low solute concentration to a region of high solute concentration across a semipermeable membrane. The number of dissolved particles contained in a unit of fluid determines the osmolality of a solution, which influences the movement of fluid between the fluid compartments. Giving a patient who has a low blood pressure a hypertonic solution will increase the number of dissolved particles in the blood, creating pressure for fluids in the tissues to shift into the capillaries and increase the blood volume. Option A is incorrect; hydrostatic pressure refers to changes in water or volume related to water pressure. Option C is incorrect; diffusion is the movement of solutes from an area of greater concentration to lesser concentration. The solutes in an intact vascular system are unable to move, so diffusion should not normally take place. Option D is incorrect; active transport is the movement of molecules against the concentration gradient and requires ATP as an energy source. This process typically takes place at the cellular level and is not involved in vascular volume changes.
Question 6 of 9
The triage nurse notes upon assessment in the emergency room that the patient with anxiety is hyperventilating. The nurse is aware that hyperventilation is the most common cause of which acid-base imbalance?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 7 of 9
A patient's lab results show a slight decrease in potassium. The physician has declined to treat with drug therapy but has suggested increasing the potassium through diet. Which of the following would be a good source of potassium?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 8 of 9
A female patient is discharged from the hospital after having an episode of heart failure. She's prescribed daily oral doses of digoxin (Lanoxin) and furosemide (Lasix). Two days later, she tells her community health nurse that she feels weak and her heart "flutters" frequently. What action should the nurse take?
Correct Answer: C
Rationale: Furosemide is a potassium-wasting diuretic. A low potassium level may cause weakness and palpitations. Telling the patient to rest more often won't help the patient if she's hypokalemic. Digoxin isn't causing the patient's symptoms, so she doesn't need to stop taking it. The patient should probably avoid caffeine, but this wouldn't resolve potassium depletion.
Question 9 of 9
The nurse in the intensive care unit receives arterial blood gases (ABG) with a patient who is complaining of being 'short of breath.' The ABG has the following values: pH = 7.21, PaCO2 = 64 mm Hg, HCO3 = 24 mm Hg. The labs reflect:
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
