which factors affect on exercise.
- A. body temperature
- B. smoking
- C. physical exercise
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D, "All of the above." Body temperature (A) is a factor as it affects how efficiently muscles work during exercise. Smoking (B) can negatively impact exercise performance and overall health. Physical exercise (C) is an obvious factor that directly influences exercise outcomes. Therefore, all three factors are interconnected and collectively influence an individual's exercise capacity and performance.

Vital capacity of lungs of an average human is
- A. 3000-4500 ml
- B. 1500-1800 ml
- C. 2000-2500 ml
- D. 500-1000 ml
Correct Answer: A
Rationale: The vital capacity of lungs is the maximum amount of air a person can exhale after a maximum inhalation. The average vital capacity for an adult human is typically between 3000-4500 ml. This range allows for efficient gas exchange in the lungs. Choice B (1500-1800 ml) and Choice C (2000-2500 ml) fall below the average vital capacity, indicating limited lung capacity. Choice D (500-1000 ml) is significantly low and would not support normal respiratory function. Therefore, Choice A (3000-4500 ml) is the correct answer as it aligns with the average vital capacity range for an average human.
A client has returned to the coronary care unit after having a coronary angiogram. Which assessment data indicate the need for immediate action by the nurse?
- A. Diminished pedal pulse volume
- B. Heart rate 100 beats/min
- C. Blood pressure 104/60 mm Hg
- D. Capillary refill less than 3 seconds
Correct Answer: A
Rationale: The correct answer is A: Diminished pedal pulse volume. This indicates potential circulation compromise, which can lead to ischemia or impaired tissue perfusion. Immediate action is required to prevent further complications. B: Heart rate 100 beats/min is within normal range. C: Blood pressure 104/60 mm Hg is slightly low but not critically concerning. D: Capillary refill less than 3 seconds indicates good peripheral perfusion.
The nasal conchae epithelial surface serves to:
- A. Warm and moisten inhaled air, via air turbulence.
- B. Help filter dust and insects from the inhaled air
- C. Recapture moisture from exhaled air to preserve fluid.
- D. All of the above are correct.
Correct Answer: D
Rationale: Rationale: The nasal conchae increase surface area, causing air turbulence to warm, moisten, and filter inhaled air. This helps in preventing respiratory issues. Choice A is correct as it explains the primary function of the conchae. Choice B is incorrect as the primary function is not filtering. Choice C is incorrect as the conchae primarily warm and moisten inhaled air rather than recapture moisture from exhaled air. Overall, choice D is correct as it encompasses all the functions of the nasal conchae.
Which of the following sinuses are located on either side of the nose?
- A. Ethmoidal sinuses
- B. Frontal sinuses
- C. Maxillary sinuses
- D. Sphenoidal sinuses
Correct Answer: C
Rationale: The correct answer is C. The maxillary sinuses are paired cavities located on either side of the nose, beneath the orbits. Ethmoidal sinuses (A) are smaller and located between the eyes. Frontal sinuses (B) are above the eyebrows. Sphenoidal sinuses (D) are deeper within the skull, behind the nasal cavity.
A male adult patient hospitalized for treatment of a pulmonary embolism develops respiratory alkalosis. Which clinical findings commonly accompany respiratory alkalosis?
- A. Nausea or vomiting
- B. Abdominal pain or diarrhea
- C. Hallucinations or tinnitus
- D. Lightheadedness or paresthesia
Correct Answer: D
Rationale: The correct answer is D: Lightheadedness or paresthesia. Respiratory alkalosis is caused by hyperventilation, leading to decreased carbon dioxide levels and an increase in pH. This can result in symptoms such as lightheadedness (from decreased cerebral blood flow) and paresthesia (tingling sensations due to changes in calcium ionization). Choices A, B, and C are incorrect as they are not typically associated with respiratory alkalosis. Nausea, vomiting, abdominal pain, and diarrhea are more commonly seen in metabolic alkalosis, while hallucinations and tinnitus are not typical symptoms of respiratory alkalosis.
