Nursing Elites

1. Which of the following arterial blood gas values indicates a patient may be experiencing a condition of metabolic acidosis?

• A. PaO2 90 mm Hg
• B. Bicarbonate 15 mEq/L
• C. CO2 47 mm Hg
• D. pH 7.34

Correct answer: B

Rationale: The correct answer is B: Bicarbonate 15 mEq/L. In metabolic acidosis, the bicarbonate levels are lower than normal. A bicarbonate value of 15 mEq/L indicates a deficit in the buffer system, contributing to the acidosis. Choices A, C, and D are incorrect. Choice A, PaO2 90 mm Hg, reflects oxygen partial pressure and is not directly related to metabolic acidosis. Choice C, CO2 47 mm Hg, represents carbon dioxide levels and is more indicative of respiratory status. Choice D, pH 7.34, falls within the normal range (7.35-7.45) and does not confirm metabolic acidosis.

2. Herbal therapy has several indications for use. Primarily, herbal therapy is:

• A. used to treat many common complaints and diseases.
• B. used to promote certain types of low-carb diets.
• C. used as an adjunct to medications.
• D. used to create a diet without salt and carbohydrates.

Correct answer: A

Rationale: The correct answer is A: 'used to treat many common complaints and diseases.' Herbal therapy is commonly used to address a variety of health issues and ailments by utilizing natural remedies derived from plants. Choices B, C, and D are incorrect because herbal therapy's primary purpose is not to promote specific diets, act as an adjunct to medications, or create specific dietary restrictions, but rather to provide alternative treatment options for various health conditions.

3. 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.

4. When dressing a severe burn to the right hand, it is important for the nurse to:

• A. Apply a wet-to-dry dressing for debridement
• B. Wrap each digit individually to prevent webbing
• C. Open blisters to allow drainage prior to dressing
• D. Allow the client to do as much of the dressing change as possible

Correct answer: B

Rationale: When dressing a severe burn to the hand, it is crucial to wrap each digit individually to prevent webbing, which can lead to contractures and impaired function. Applying a wet-to-dry dressing for debridement is not recommended for burn wounds as it can cause trauma to the wound bed during removal. Opening blisters can increase the risk of infection and delay healing. Allowing the client to perform the dressing change may not ensure proper care and can lead to complications.

5. A 55-year-old female asks a nurse the following, “Which mineral/vitamin is the most important to prevent the progression of osteoporosis?” The nurse should state:

• A. Potassium
• B. Magnesium
• C. Calcium
• D. Vitamin B12

Correct answer: C

Rationale: The correct answer is C: Calcium. Calcium is essential for maintaining bone health and is crucial in preventing osteoporosis. Adequate calcium intake, along with vitamin D, is vital for bone strength. While other minerals and vitamins are also important for overall health, in the context of preventing osteoporosis, calcium plays a primary role. Potassium (Choice A), Magnesium (Choice B), and Vitamin B12 (Choice D) are important for various bodily functions but are not as directly linked to preventing osteoporosis as calcium.
