Nursing Elites

1. A nurse is taking the health history of an 85-year-old client. Which of the following physical findings is consistent with normal aging?

• A. Increase in subcutaneous fat.
• B. Diminished cough reflex.
• C. Long-term memory loss.
• D. Myopia.

Correct answer: B

Rationale: The correct answer is 'Diminished cough reflex.' Diminished cough reflex is a physical finding consistent with normal aging in older adults, which can increase the risk of aspiration and atelectasis. An increase in subcutaneous fat actually raises the risk of pressure ulcers. While long-term memory is typically preserved in aging unless affected by dementia, short-term memory often declines. Myopia (near-sightedness) is common in younger individuals, but presbyopia (far-sightedness) is more common with aging. Additionally, individuals with myopia may experience an improvement in vision as they age.

2. A client has chronic respiratory acidosis caused by end-stage chronic obstructive pulmonary disease (COPD). Oxygen is delivered at 1 L/min via nasal cannula. The nurse teaches the family that the reason for this is to avoid respiratory depression, based on which of the following explanations?

• A. COPD clients are stimulated to breathe by hypoxia.
• B. COPD clients depend on a low carbon dioxide level.
• C. COPD clients tend to retain hydrogen ions if they are given high doses of oxygen.
• D. COPD clients thrive on a high oxygen level.

Correct answer: A

Rationale: In clients with COPD and chronic respiratory acidosis, they are compensating for low oxygen and high carbon dioxide levels. Hypoxia acts as the main stimulus to breathe in individuals with chronic hypercapnia. When oxygen is administered, it can decrease the respiratory drive by eliminating the hypoxic drive and reducing the stimulus to breathe. Therefore, delivering oxygen at 1 L/min via nasal cannula helps prevent respiratory depression by maintaining the hypoxic drive to breathe. The other options are incorrect: COPD clients do not depend on a low carbon dioxide level as they are chronically hypercapnic, they do not retain hydrogen ions with high oxygen doses, and they do not thrive on a high oxygen level.

3. 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.

4. What skin color does a client with jaundice have?

• A. pale
• B. ruddy
• C. yellow
• D. pink

Correct answer: C

Rationale: The correct answer is C: yellow. Jaundice is a condition characterized by yellowing of the skin due to increased levels of bilirubin in the blood. This excess bilirubin causes the skin and whites of the eyes to appear yellow. Choice A, pale, is not typically associated with jaundice. Choice B, ruddy, describes a reddish skin color and is not indicative of jaundice. Choice D, pink, is a normal skin color and not a symptom of jaundice.

5. A patient has been prescribed Tegretol for the first time. Which of the following side effects is not associated with Tegretol?

• A. Sore throat
• B. Vertigo
• C. Fever
• D. Shortness of breath

Correct answer: D

Rationale: The correct answer is 'Shortness of breath.' Side effects commonly associated with Tegretol include sore throat, vertigo, and fever. Shortness of breath is not a typical side effect of Tegretol use. Sore throat, vertigo, and fever are known side effects of Tegretol, while shortness of breath is not typically linked to its use.
