1. What is the primary action of insulin in the body?

• A. To lower blood pressure.
• B. To promote the absorption of glucose into cells.
• C. To increase blood glucose levels.
• D. To decrease blood glucose levels.

Correct answer: B

Rationale: The correct answer is B: To promote the absorption of glucose into cells. Insulin facilitates the uptake of glucose by cells, thereby decreasing blood glucose levels. Choice A is incorrect as insulin does not directly affect blood pressure. Choice C is inaccurate as insulin works to lower, not increase, blood glucose levels. Choice D is incorrect because insulin's primary role is to lower, not increase, blood glucose levels by promoting glucose uptake into cells.

2. The client who has a history of Parkinson's disease for the past 5 years is being assessed by the nurse. What symptoms would this client most likely exhibit?

• A. Loss of short-term memory, facial tics, and grimaces, and constant writhing movements.
• B. Shuffling gait, masklike facial expression, and tremors of the head.
• C. Extreme muscular weakness, easy fatigability, and ptosis.
• D. Numbness of the extremities, loss of balance, and visual disturbances.

Correct answer: B

Rationale: Parkinson's Disease, a common neurologic progressive disorder in older clients, is characterized by symptoms such as shuffling gait, masklike facial expression, and tremors of the head and hands. Choice A is incorrect as symptoms like loss of short-term memory, facial tics, and constant writhing movements are not typically associated with Parkinson's disease. Choice C is incorrect as extreme muscular weakness, easy fatigability, and ptosis are more indicative of other conditions like myasthenia gravis. Choice D is incorrect as numbness of the extremities, loss of balance, and visual disturbances are not classic symptoms of Parkinson's disease.

3. Which of the following is a common cause of acute kidney injury?

• A. Hypertension
• B. Dehydration
• C. Infection
• D. Hypotension

Correct answer: C

Rationale: Infection is a common cause of acute kidney injury because when the body fights an infection, it activates the immune response, leading to inflammation. This inflammatory response can affect the kidneys and impair their function. While hypertension (choice A) is a risk factor for chronic kidney disease, it is not a direct cause of acute kidney injury. Dehydration (choice B) can lead to prerenal acute kidney injury due to decreased blood flow to the kidneys, but infection is a more common cause of acute kidney injury. Hypotension (choice D) can contribute to prerenal acute kidney injury, but it is not a direct cause like infection.

4. A client with a history of peptic ulcer disease (PUD) is admitted after vomiting bright red blood several times over the course of 2 hours. In reviewing the laboratory results, the nurse finds the client's hemoglobin is 12 g/dL (120g/L) and the hematocrit is 35% (0.35). Which action should the nurse prepare to take?

• A. Continue monitoring for blood loss
• B. Administer 1,000 mL (1L) of normal saline
• C. Transfuse 2 units of platelets
• D. Prepare the client for emergency surgery

Correct answer: D

Rationale: The correct answer is to prepare the client for emergency surgery. The client's presentation with bright red blood in vomitus suggests active bleeding, which is a medical emergency. With a hemoglobin of 12 g/dL and a hematocrit of 35%, the client is likely experiencing significant blood loss that may require surgical intervention to address the source of bleeding. Continuing to monitor for blood loss (Choice A) is not appropriate in this acute situation where immediate action is necessary. Administering normal saline (Choice B) may help with fluid resuscitation but does not address the underlying cause of bleeding. Transfusing platelets (Choice C) is not indicated in this scenario as platelets are involved in clot formation and are not the primary treatment for active bleeding in this context.

5. A marathon runner comes into the clinic and states, 'I have not urinated very much in the last few days.' The nurse notes a heart rate of 110 beats/min and a blood pressure of 86/58 mm Hg. Which action by the nurse is the priority?

• A. Give the client a bottle of water immediately.
• B. Start an intravenous line for fluids.
• C. Teach the client to drink 2 to 3 liters of water daily.
• D. Perform an electrocardiogram.

Correct answer: A

Rationale: The priority action for the nurse is to give the client a bottle of water immediately. The athlete's symptoms of decreased urination, along with a heart rate of 110 beats/min and low blood pressure of 86/58 mm Hg, indicate mild dehydration. Rehydration should begin promptly to address the dehydration. Teaching the client to drink 2 to 3 liters of water daily is a good long-term strategy but not the immediate priority. Starting an intravenous line for fluids may be necessary if oral hydration is insufficient or if the degree of dehydration is severe. Performing an electrocardiogram is not indicated at this time as the priority is addressing the dehydration.
