Nursing Elites

1. A client with a history of hypertension is prescribed hydrochlorothiazide (HCTZ). Which adverse effect should the nurse monitor for?

• A. Hyperkalemia
• B. Hyponatremia
• C. Bradycardia
• D. Hyperglycemia

Correct answer: B

Rationale: The correct answer is 'B. Hyponatremia.' Hydrochlorothiazide can lead to electrolyte imbalances, such as hyponatremia, due to its diuretic effect. This potential adverse effect should be closely monitored in patients taking HCTZ. Choice A, hyperkalemia, is less likely to occur with HCTZ as it tends to cause hypokalemia. Choice C, bradycardia, is not a common adverse effect of HCTZ. Choice D, hyperglycemia, is also less commonly associated with HCTZ use compared to hyponatremia.

2. What is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space?

• A. Filtration
• B. Diffusion
• C. Osmosis
• D. Active transport

Correct answer: C

Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.

3. 4 hours after administration of 20U of regular insulin, the client becomes shaky and diaphoretic. What action should the nurse take?

• A. Encourage the client to eat crackers and milk
• B. Administer a PRN dose of 10U of regular insulin
• C. Give the client crackers and milk
• D. Record the client's reaction in the diabetic flow sheet

Correct answer: C

Rationale: The correct action for the nurse to take when a client becomes shaky and diaphoretic after insulin administration, indicating hypoglycemia, is to provide the client with carbohydrates like crackers and milk. Carbohydrates help raise blood glucose levels quickly. Encouraging the client to eat crackers and milk (Choice A) is the appropriate immediate action to address the hypoglycemia. Administering more insulin (Choice B) would worsen hypoglycemia, and recording the reaction (Choice D) is important but not the immediate action needed to treat the hypoglycemia.

4. What is the primary purpose of a chest tube in a client's care?

• A. To drain air and fluid from the pleural space
• B. To prevent infection in the thoracic cavity
• C. To assist with lung expansion
• D. To monitor intrathoracic pressure

Correct answer: A

Rationale: The correct answer is A: To drain air and fluid from the pleural space. A chest tube is primarily used to remove accumulated air or fluid in the pleural space, preventing lung collapse or compromise of lung function. This intervention aims to re-expand the lung and enhance respiratory function. Choice B is incorrect because preventing infection is not the primary purpose of a chest tube. Choice C is incorrect as lung expansion is a result of draining the pleural space, not the primary goal. Choice D is incorrect as monitoring intrathoracic pressure is not the main objective of a chest tube insertion.

5. During a tonic-clonic seizure, what is the nurse's priority intervention?

• A. Insert an oral airway
• B. Administer oxygen via nasal cannula
• C. Restrain the client's arms and legs
• D. Protect the client's head from injury

Correct answer: D

Rationale: During a tonic-clonic seizure, the nurse's priority intervention is to protect the client's head from injury. This is crucial to prevent trauma, as head injuries can be severe during a seizure. Inserting an oral airway may cause injury or obstruction during the seizure and is not recommended. Administering oxygen via nasal cannula can be done after ensuring the client's safety. Restraining the client's arms and legs is also not recommended as it can lead to further injury or harm.
