Nursing Elites

1. Which symptoms is the client who overdosed on barbiturates most likely to exhibit?

• A. Bradypnea and bradycardia
• B. Hyperthermia and drowsiness
• C. Hyperreflexia and slurred speech
• D. Tachycardia and psychosis

Correct answer: A

Rationale: The correct answer is bradypnea and bradycardia. Barbiturates are central nervous system (CNS) depressants, which will slow down the respiratory rate (bradypnea) and heart rate (bradycardia). Choice B, hyperthermia and drowsiness, is incorrect as barbiturate overdose typically does not cause hyperthermia but rather hypothermia. Hyperreflexia and slurred speech (Choice C) are more indicative of stimulant overdoses rather than CNS depressants like barbiturates. Tachycardia and psychosis (Choice D) are also not typically seen in barbiturate overdose, as these drugs tend to depress the CNS rather than cause symptoms of increased heart rate or psychosis.

2. Metformin (Glucophage) is administered to clients with type II diabetes mellitus. Metformin is an example of:

• A. an antihyperglycemic agent.
• B. a hypoglycemic agent.
• C. an insulin analogue.
• D. a pancreatic alpha cell stimulant

Correct answer: A

Rationale: Metformin is classified as an antihyperglycemic agent because it works by reducing hepatic glucose output and decreasing glucose absorption from the gut, thereby preventing hyperglycemia. Choice B, a hypoglycemic agent, is incorrect as hypoglycemic agents stimulate insulin production, which is not the mechanism of action of metformin. Choice C, an insulin analogue, is incorrect as metformin is not a type of insulin but a distinct medication. Choice D, a pancreatic alpha cell stimulant, is incorrect as metformin does not stimulate any pancreatic cells, but rather acts on the liver and gut to lower blood sugar levels.

3. A healthcare professional is assessing a patient's right lower extremity. The extremity is warm to touch, red, and swollen. The patient is also running a low fever. Which of the following conditions would be the most likely cause of the patient's condition?

• A. Herpes
• B. Scleroderma
• C. Dermatitis
• D. Cellulitis

Correct answer: D

Rationale: The patient's presentation of a warm, red, swollen extremity with a low fever is indicative of cellulitis, which is inflammation of cellular tissue. Cellulitis is commonly associated with these symptoms due to a bacterial infection in the skin and underlying tissues. Herpes (Choice A) is a viral infection that typically presents with grouped vesicles, not the warm, red, swollen presentation seen in cellulitis. Scleroderma (Choice B) is a chronic autoimmune condition affecting the skin and connective tissue, presenting differently from the acute symptoms of cellulitis. Dermatitis (Choice C) refers to skin inflammation, which does not typically present with the described symptoms of warmth, redness, swelling, and low fever observed in cellulitis.

4. A 22-year-old patient in a mental health lock-down unit under suicide watch appears happy about being discharged. Which of the following is probably happening?

• A. The patient is excited about being around family again.
• B. The patient's suicide plan has probably progressed.
• C. The patient's plans for the future have been clarified.
• D. The patient's mood is improving.

Correct answer: B

Rationale: In this scenario, it is concerning that a patient under suicide watch is happy about being discharged as it may indicate that the patient's suicide plan has advanced. This change in behavior should be taken seriously as it can signal an increased risk of self-harm. Choices A, C, and D are less likely as the patient's happiness about discharge in this context is more indicative of a worsening situation rather than positive outcomes like being around family, clarifying future plans, or improving mood.

5. A client with asthma develops respiratory acidosis. Based on this diagnosis, what should the nurse expect the client's serum potassium level to be?

• A. normal
• B. elevated
• C. low
• D. unrelated to the pH

Correct answer: B

Rationale: In respiratory acidosis, the body retains CO2, leading to increased hydrogen ion concentration and a drop in blood pH. As pH decreases, serum potassium levels increase due to the movement of potassium out of cells to compensate for the acidosis. Elevated serum potassium levels are expected in respiratory acidosis. Choice A ('normal') is incorrect because potassium levels are expected to be elevated in respiratory acidosis. Choice C ('low') is incorrect as potassium levels rise in this condition. Choice D ('unrelated to the pH') is incorrect as serum potassium levels are directly impacted by changes in pH in respiratory acidosis.
