Nursing Elites

1. A client goes to the Emergency Department with acute respiratory distress and the following arterial blood gases (ABGs): pH 7.35, PCO2 40 mmHg, PO2 63mmHg, HCO3 23, and oxygenation saturation (SAO2) 93%. Which of the following represents the best analysis of the etiology of these ABGs?

• A. tuberculosis (TB)
• B. pneumonia
• C. pleural effusion
• D. hypoxia

Correct answer: D

Rationale: A combined low PO2 and low SAO2 indicates hypoxia. The pH, PCO2, and HCO3 are normal. ABGs are not necessarily altered in TB or pleural effusion. In pneumonia, the PO2 and PCO2 might be low because hypoxia stimulates hyperventilation, but the best analysis in this case is hypoxia due to the combination of low PO2 and low SAO2.

2. When administering intravenous electrolyte solution, which of the following precautions should the nurse take?

• A. Infuse hypertonic solutions cautiously.
• B. Mix no more than 60 mEq of potassium per liter of fluid.
• C. Prevent infiltration of calcium, which causes tissue necrosis and sloughing.
• D. Monitor the client's digitalis dosage for potential adjustments due to IV calcium administration.

Correct answer: C

Rationale: When administering intravenous electrolyte solutions, it is crucial to prevent infiltration of calcium to avoid tissue necrosis and sloughing. Hypertonic solutions should be infused cautiously (Choice A) to prevent adverse effects. The correct amount of potassium to be mixed in a liter of fluid is no more than 60 mEq, making Choice B incorrect. While monitoring the client's digitalis dosage for potential adjustments due to IV calcium administration is important, the statement suggesting an increased dosage is incorrect as IV calcium diminishes digitalis's action, making Choice D incorrect.

3. What vitamin is important in preventing peripheral neuritis in a client with alcohol abuse?

• A. Vitamin D
• B. Fat-soluble vitamins
• C. B vitamins
• D. Potassium

Correct answer: B

Rationale: The correct answer is 'Fat-soluble vitamins.' Vitamin B, not Vitamin D, is crucial in preventing peripheral neuritis in individuals with alcohol abuse. Vitamin B deficiency, particularly B1 (thiamine), is commonly associated with peripheral neuritis in alcoholics. Therefore, choices A, C, and D are incorrect. Vitamin D is not directly related to peripheral neuritis, and potassium deficiency typically presents with different symptoms.

4. Which type of cells secrete insulin?

• A. alpha cells
• B. beta cells
• C. CD4 cells
• D. helper cells

Correct answer: B

Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.

5. A 20-year-old obese female client is preparing to have gastric bypass surgery for weight loss. She says to the nurse, "I need this surgery because nothing else I have done has helped me to lose weight."? Which response by the nurse is most appropriate?

• A. "If you eat less, you can save some money."?
• B. "Exercise is a healthier way to lose weight."?
• C. "You should try the Atkins diet first."?
• D. "I respect your decision to choose surgery."?

Correct answer: D

Rationale: The most appropriate response by the nurse is to show respect and empathy towards the client's decision. Option D acknowledges the client's autonomy and decision-making process, fostering a therapeutic relationship. Options A, B, and C are insensitive and unprofessional. Option A implies a financial incentive for weight loss, which can be perceived as disrespectful and trivializing the client's concerns. Option B suggests an alternative method without considering the client's reasons for choosing surgery, potentially invalidating her experiences. Option C recommends a specific diet without addressing the client's concerns or choices, neglecting her autonomy in decision-making.
