Question 1 of 5
A nurse is suctioning fluids from a male client via a tracheostomy tube. When suctioning, the nurse must limit the suctioning time to a maximum of:
Correct Answer: C
Rationale: The correct answer is C: 10 seconds. Suctioning time for a tracheostomy tube should be limited to 10 seconds to prevent hypoxia and tissue damage. Prolonged suctioning can lead to decreased oxygenation and potential trauma to the airway. Choice A (1 minute) is too long and can cause harm. Choice B (5 seconds) is too short to effectively clear secretions. Choice D (30 seconds) exceeds the recommended time limit and can lead to complications. Therefore, limiting suctioning time to 10 seconds is the safest and most effective approach.
Question 2 of 5
Which of the following instructions should the nurse give a client about his active tuberculosis (TB)?
Correct Answer: D
Rationale: The correct answer is D because adherence to the medication regimen is crucial in treating active TB to prevent drug resistance and ensure successful treatment. Missing doses can lead to treatment failure and the spread of TB. Option A is incorrect because missing doses compromises treatment effectiveness. Option B is incorrect as stopping medication due to side effects can also result in treatment failure. Option C is incorrect because TB treatment must be completed as prescribed, regardless of symptom improvement.
Question 3 of 5
The atmospheric pressure at sea level is
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.
Question 4 of 5
Although carbon dioxide is normally carried by hemoglobin, the fact that carbon monoxide reduces hemoglobin's oxygen-carrying capacity would indicate that
Correct Answer: B
Rationale: The correct answer is B because carbon monoxide competes with oxygen for the same binding sites on hemoglobin, leading to reduced oxygen-carrying capacity. This is known as competitive inhibition. Other choices are incorrect because different hemoglobins do not carry different gases (A), binding of gases is not directed by enzymes in this context (C), and carbon dioxide is a normal gas in the body (D).
Question 5 of 5
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
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.
