Nursing Elites

1. The client is advised to take dexamethasone (Decadron) with food or milk. What is the physiological basis for this advice?

• A. Inhibits pepsin production
• B. Stimulates hydrochloric acid production
• C. Delays stomach emptying time
• D. Reduces hydrochloric acid production

Correct answer: B

Rationale: The correct answer is B: Stimulates hydrochloric acid production. Dexamethasone can stimulate the production of hydrochloric acid in the stomach, which may lead to irritation of the stomach lining. Taking dexamethasone with food or milk helps to neutralize or buffer the acid, reducing the risk of stomach irritation. Choice A is incorrect because dexamethasone does not inhibit pepsin production. Choice C is incorrect as dexamethasone does not slow stomach emptying time. Choice D is incorrect as dexamethasone does not reduce hydrochloric acid production.

2. A nurse on a medical-surgical unit is caring for a group of clients. The nurse should identify that which of the following clients is at risk for hypovolemia?

• A. A client who has nasogastric suctioning
• B. A client who has chronic constipation
• C. A client who has syndrome of inappropriate antidiuretic hormone
• D. A client who took a toxic dose of sodium bicarbonate antacids

Correct answer: A

Rationale: The correct answer is A. Nasogastric suctioning can lead to hypovolemia due to the loss of gastric fluids. Chronic constipation and syndrome of inappropriate antidiuretic hormone (SIADH) are not typically associated with hypovolemia. A toxic dose of sodium bicarbonate antacids may lead to metabolic alkalosis, not hypovolemia.

3. The nurse is providing care for a client who is receiving total parenteral nutrition (TPN). Which laboratory value should the nurse monitor closely to assess for complications?

• A. Serum potassium
• B. Blood glucose
• C. Serum sodium
• D. Serum calcium

Correct answer: B

Rationale: The correct answer is B: Blood glucose. When caring for a client receiving total parenteral nutrition (TPN), monitoring blood glucose levels is essential due to the increased risk of hyperglycemia associated with TPN infusion. Elevated blood glucose levels can lead to complications such as hyperglycemia, which can be harmful to the client. While monitoring serum potassium (Choice A), serum sodium (Choice C), and serum calcium (Choice D) are also important aspects of care, when specifically considering TPN administration, blood glucose monitoring takes precedence due to the potential for significant complications related to glucose imbalances.

4. What is the most important assessment for the LPN/LVN to perform on a client with a history of chronic obstructive pulmonary disease (COPD) receiving oxygen therapy at 2 liters per minute via nasal cannula?

• A. Assess the client's respiratory rate and effort.
• B. Measure the client's oxygen saturation level.
• C. Monitor the client's arterial blood gas levels.
• D. Check the client's blood pressure.

Correct answer: B

Rationale: Measuring the client's oxygen saturation level is the most important assessment in this scenario. Oxygen saturation level reflects how well the client is oxygenating, which is crucial in assessing the effectiveness of oxygen therapy for a client with COPD. Monitoring the respiratory rate and effort (Choice A) is important but assessing oxygenation with saturation levels takes precedence. While arterial blood gas levels (Choice C) provide comprehensive information, checking oxygen saturation is a quicker and more immediate way to assess oxygenation status. Checking blood pressure (Choice D) is not the priority when evaluating the effectiveness of oxygen therapy in COPD.

5. The nurse is preparing to administer a subcutaneous injection of enoxaparin (Lovenox). Which site is most appropriate for the LPN/LVN to use?

• A. Deltoid muscle
• B. Ventrogluteal site
• C. Abdomen
• D. Dorsogluteal site

Correct answer: C

Rationale: The abdomen is the most appropriate site for administering subcutaneous injections of enoxaparin (Lovenox). Enoxaparin is typically administered in the abdomen due to better absorption and reduced risk of injury to underlying structures. The deltoid muscle is not recommended for subcutaneous injections of enoxaparin due to the potential risk of injury to underlying structures. The ventrogluteal and dorsogluteal sites are more appropriate for intramuscular injections rather than subcutaneous injections.
