Nursing Elites

1. A client who had surgery yesterday is becoming increasingly anxious. The client’s respiratory rate has increased to 38 breaths/minute. The client has a nasogastric tube to low intermittent suction with 500 ml of yellow-green drainage over the last four hours. The client's arterial blood gases (ABGs) indicate a decreased CO2 and an increased serum pH. Which serum laboratory value should the nurse monitor first?

• A. Electrolytes.
• B. Creatinine.
• C. Blood urea nitrogen.
• D. Glucose.

Correct answer: A

Rationale: The correct answer is A, Electrolytes. In this scenario, the client is at risk for metabolic alkalosis due to the loss of gastric secretions through the nasogastric tube. Monitoring electrolytes is crucial to assess the levels of sodium, potassium, chloride, and bicarbonate, which are important in maintaining the acid-base balance of the body. Changes in these electrolyte levels can provide valuable information about the client's fluid status and acid-base balance. Creatinine, blood urea nitrogen, and glucose levels are important parameters to monitor in different situations but are not the priority in this case of potential metabolic alkalosis.

2. The mother of a child with acute laryngotracheobronchitis (LTB) asks why her child must be kept NPO. Which response would be the most correct?

• A. The epinephrine given causes nausea and vomiting.
• B. The child is being hydrated with IV fluids.
• C. The child is not hungry.
• D. The child's rapid respirations pose a risk for aspiration.

Correct answer: D

Rationale: The correct answer is D because rapid respirations predispose to aspiration in a child with acute laryngotracheobronchitis. Choice A is incorrect because epinephrine does not directly relate to the need for NPO status. Choice B is incorrect as hydration with IV fluids is not the primary reason for keeping the child NPO. Choice C is incorrect as the child being hungry is not the main concern when keeping a child NPO in this situation.

3. A client with diabetes mellitus is experiencing polyuria, polydipsia, and polyphagia. What do these symptoms indicate?

• A. Hypoglycemia
• B. Diabetic ketoacidosis (DKA)
• C. Hyperosmolar hyperglycemic state (HHS)
• D. Insulin shock

Correct answer: B

Rationale: Polyuria, polydipsia, and polyphagia are classic signs of diabetic ketoacidosis (DKA), which occurs due to a combination of hyperglycemia and ketone production. Hypoglycemia (Choice A) is characterized by low blood sugar levels, leading to symptoms like confusion, shakiness, and sweating, which are different from the symptoms described in the scenario. Hyperosmolar hyperglycemic state (HHS) (Choice C) typically presents with severe hyperglycemia, dehydration, and altered mental status, rather than the triad of symptoms mentioned. Insulin shock (Choice D) refers to a severe hypoglycemic reaction due to excessive insulin, manifesting with confusion, sweating, and rapid heartbeat, not the symptoms seen in the client with diabetes mellitus described in this scenario.

4. When caring for a 7-week-old infant with hypothyroidism, the nurse explains that the prevention of what complication is dependent on the administration of oral thyroid replacement therapy and is critical for the child?

• A. Excessive growth
• B. Cognitive impairment
• C. Damage to the nervous system
• D. Damage to the urinary system

Correct answer: B

Rationale: The correct answer is B: Cognitive impairment. The treatment of choice for congenital and acquired hypothyroidism is oral thyroid hormone replacement therapy. Prompt treatment is especially critical in the infant with congenital hypothyroidism to avoid permanent cognitive impairment. Excessive growth (Choice A) is not a common complication of hypothyroidism in infants. Damage to the nervous system (Choice C) and damage to the urinary system (Choice D) are not typically associated with untreated hypothyroidism in infants.

5. A client who is experiencing respiratory distress is admitted with respiratory acidosis. Which pathophysiological process supports the client’s respiratory acidosis?

• A. Low oxygen levels are present in the blood.
• B. High levels of carbon dioxide have accumulated in the blood.
• C. Increased bicarbonate levels are causing alkalosis.
• D. Respiratory rate is increased, causing hyperventilation.

Correct answer: B

Rationale: High levels of carbon dioxide in the blood lead to respiratory acidosis due to inadequate ventilation. The correct answer is B. In respiratory acidosis, the accumulation of carbon dioxide in the blood occurs due to inadequate exhalation, leading to acidosis. Choice A is incorrect as low oxygen levels are related to hypoxemia, not respiratory acidosis. Choice C is incorrect as increased bicarbonate levels would lead to alkalosis, not acidosis. Choice D is incorrect as an increased respiratory rate causing hyperventilation would actually help decrease carbon dioxide levels, not lead to respiratory acidosis.
