Which of the following signs may be revealed in a client with tonsillar infection by a visual examination if group A streptococci is the cause?
- A. White patches on the tonsils
- B. Hemorrhage in the tonsils
- C. Hypertrophied tonsils
- D. Bleeding in the tonsils
Correct Answer: A
Rationale: The correct answer is A. White patches on the tonsils are characteristic of streptococcal infections, such as strep throat. B (hemorrhage) and D (bleeding) are not typical findings in streptococcal infections. C (hypertrophied tonsils) may occur but is not specific to group A streptococci.

The atmospheric pressure at sea level is
- A. 1,000mm Hg.
- B. 760mm Hg.
- C. 540mm Hg.
- D. 400mm Hg.
Correct Answer: B
Rationale: The atmospheric pressure at sea level is typically around 760mm Hg, which is equivalent to 101.3 kilopascals. This is the standard atmospheric pressure used in various scientific calculations. This value represents the pressure exerted by the weight of air above a given area at sea level. Choice B is correct because it accurately reflects the standard atmospheric pressure at sea level. Choices A, C, and D are incorrect as they do not match the accepted value for atmospheric pressure at sea level.
A nurse teaches a client who is prescribed nicotine replacement therapy. Which statement should the nurse include in this client's teaching?
- A. Make a list of reasons why smoking is a bad habit.
- B. Rise slowly when getting out of bed in the morning.
- C. Smoking while taking this medication will increase your risk of a stroke.
- D. Stopping this medication suddenly increases your risk for a heart attack.
Correct Answer: C
Rationale: The correct answer is C. Smoking while taking nicotine replacement therapy can increase the risk of a stroke due to the combination of nicotine intake from smoking and the therapy. This is important for the client to understand to avoid potential serious health complications.
A: Making a list of reasons why smoking is bad is not directly related to the client's use of nicotine replacement therapy.
B: Rising slowly when getting out of bed is a general safety measure and not specific to nicotine replacement therapy.
D: Stopping nicotine replacement therapy suddenly does not increase the risk for a heart attack; rather, it may lead to withdrawal symptoms.
Oxygen dissociation curve shows the relation between
- A. Oxyhemoglobin saturation and Oxygen tension
- B. Oxyhemoglobin saturation and Carbon dioxide level
- C. Oxyhemoglobin formation and dissociation
- D. Partial pressure of Oxygen and Partial pressure of Carbon dioxide
Correct Answer: A
Rationale: The oxygen dissociation curve illustrates the relationship between oxyhemoglobin saturation and oxygen tension. As oxygen tension increases, hemoglobin binds more oxygen until it becomes fully saturated. Option A is correct as it accurately describes this relationship. Option B is incorrect because carbon dioxide level does not directly affect the oxygen-hemoglobin binding. Option C is incorrect as it does not reflect the relationship shown by the curve. Option D is incorrect because it mixes the variables of oxygen and carbon dioxide, which are not directly related in the oxygen dissociation curve.
The inspiratory capacity is a total of what two pulmonary volumes?
- A. tidal volume and inspiratory reserve volume
- B. vital capacity and tidal volume
- C. vital capacity and inspiratory reserve volume
- D. residual volume and tidal volume
Correct Answer: A
Rationale: The inspiratory capacity is the maximum volume of air that can be inhaled after a normal exhalation. It is the sum of tidal volume and inspiratory reserve volume. Tidal volume is the volume of air inhaled and exhaled during normal breathing, while inspiratory reserve volume is the additional air that can be inhaled after a normal inhalation. Therefore, the correct answer is A.
Summary of why other choices are incorrect:
B: Vital capacity is the maximum volume of air that can be exhaled after a maximum inhalation. It does not include tidal volume, so this choice is incorrect.
C: Vital capacity includes inspiratory reserve volume, not tidal volume, so this choice is incorrect.
D: Residual volume is the volume of air remaining in the lungs after maximal exhalation, not part of inspiratory capacity. Tidal volume is the only correct component in this choice.
A person met with an accident and died instantly without any injury to heart, brain, stomach and kidney. One of the following is a reason for his death
- A. Intestine got twisted
- B. RBC became coagulated
- C. Stomach stopped digestion
- D. Diaphragm got punctured
Correct Answer: D
Rationale: The correct answer is D: Diaphragm got punctured. The diaphragm is a crucial muscle responsible for breathing. If it gets punctured, it can lead to immediate death due to respiratory failure. In this scenario, since there are no injuries to vital organs like the heart, brain, stomach, or kidney, the only plausible reason for instant death would be a punctured diaphragm affecting the person's ability to breathe.
A: Intestine getting twisted would not lead to instant death without affecting the heart, brain, stomach, or kidney.
B: RBC becoming coagulated would not result in immediate death without directly impacting vital organs.
C: Stomach stopping digestion is not a life-threatening condition that would cause instant death without injury to vital organs.
