Question 1 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 2 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 3 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.
Question 4 of 5
Oxygen and carbon dioxide concentration in the alveolar air is respectively
Correct Answer: D
Rationale: The correct answer is D (13.1% oxygen and 5% carbon dioxide). In the alveolar air, the oxygen concentration is around 13.1%, which is lower than atmospheric air (21%) due to gas exchange in the lungs. The carbon dioxide concentration in alveolar air is around 5%, higher than atmospheric air (0.04%). Choices A, B, and C have oxygen concentrations higher than what is found in alveolar air, making them incorrect. Choice B also has a carbon dioxide concentration higher than what is typically found in alveolar air, making it incorrect.
Question 5 of 5
A nurse assesses a client after an open lung biopsy. Which assessment finding is matched with the correct intervention?
Correct Answer: C
Rationale: The correct answer is C. Reduced breath sounds after an open lung biopsy could indicate a potential complication such as pneumothorax, requiring immediate attention. Calling the primary health care provider allows for timely assessment and intervention. Choice A is incorrect because dizziness alone may not warrant calling the Rapid Response Team without further assessment. Choice B is incorrect as a heart rate of 55 beats/min may not necessarily indicate a need to withhold pain medication without considering other factors. Choice D is incorrect as a respiratory rate of 18 breaths/min does not necessarily mean the oxygen flow rate should be decreased without further assessment.
