Which of the following is TRUE about the mechanism of action of the Aortic and Carotid bodies?
- A. If the BP is elevated, the RR increases
- B. If the BP is elevated, the RR decreases
- C. Elevated BP leads to Metabolic alkalosis
- D. Low BP leads to Metabolic acidosis
Correct Answer: B
Rationale: Aortic and carotid bodies, chemoreceptors, slow respiration when BP rises e.g., baroreceptors signal reduced need for O2 delivery. Increased RR (hypoxia), alkalosis (pH), or acidosis (metabolic) misalign. Nurses note this e.g., in hypertension for respiratory adjustments, per cardiovascular interplay.

A client has a new diagnosis of osteoarthritis and is being taught about dietary management. Which of the following statements should be included in the teaching?
- A. Increase your intake of calcium-rich foods.
- B. Avoid foods that are high in potassium.
- C. Increase your intake of vitamin D-rich foods.
- D. Avoid foods that are high in sodium.
Correct Answer: C
Rationale: The correct statement to include in the teaching is to increase the intake of vitamin D-rich foods. Vitamin D helps improve calcium absorption, which is beneficial for bone health and may help alleviate symptoms of osteoarthritis. Option A is incorrect because while calcium is important for bone health, the focus should be on vitamin D for calcium absorption. Option B is incorrect as potassium is generally not restricted in osteoarthritis. Option D is also incorrect as sodium restriction is more relevant for conditions like hypertension or heart failure, not specifically for osteoarthritis.
Which of the following statement is TRUE about telemedicine?
- A. Requires in-person visit
- B. Use of technology for remote care
- C. Limited to hospital settings
- D. All of the above
Correct Answer: B
Rationale: Telemedicine uses technology for remote care (B), per definition e.g., virtual consults. Not in-person (A), not hospital-only (C), not all (D) distance-based. B truly defines telemedicine's reach, making it correct.
The nurse is teaching the client with insulin-dependent diabetes the signs of hypoglycemia. Which of the following signs is associated with hypoglycemia?
- A. Tremulousness
- B. Slow pulse
- C. Nausea
- D. Flushed skin
Correct Answer: A
Rationale: Tremulousness is a classic sign of hypoglycemia in insulin-dependent diabetes, resulting from the autonomic nervous system's response to low glucose, triggering adrenaline release shakiness signals urgent need for sugar. Slow pulse, nausea, or flushed skin align more with other conditions or hyperglycemia. Nurses teach this symptom for self-recognition, enabling rapid intervention with glucose sources, preventing severe outcomes like seizures, critical for diabetes management.
A client with a new diagnosis of chronic kidney disease is being taught about dietary management. Which of the following statements should be included in the teaching?
- A. Increase your intake of protein-rich foods.
- B. Decrease your intake of phosphorus-rich foods.
- C. Avoid foods that contain lactose.
- D. Increase your intake of potassium-rich foods.
Correct Answer: B
Rationale: In chronic kidney disease, decreasing the intake of phosphorus-rich foods is essential as impaired kidney function can lead to difficulty in excreting phosphorus, causing an imbalance. This can result in bone and heart complications. Therefore, educating the client to reduce phosphorus intake is crucial for managing the disease and preventing further complications. Option A is incorrect because excessive protein intake can burden the kidneys. Option C is not directly related to the management of chronic kidney disease. Option D is also incorrect as potassium intake may need to be limited in certain stages of kidney disease.
Which of the following situation best describe an ethical dilemma?
- A. The nurse is not sure what time to give the medication
- B. The client refuses a procedure that can save his life
- C. The client asks what his diagnosis is
- D. The nurse forgot to give the medication
Correct Answer: B
Rationale: Client refusing a life-saving procedure (B) is an ethical dilemma autonomy vs. beneficence, per ethics. Timing (A) and forgetting (D) are errors, asking diagnosis (C) routine. B's conflicting principles best exemplify a dilemma, making it correct.
