Question 1 of 5
Which one is not correct? A patient suffering from anaemia with an Hb concentration of 5g/100ml
Correct Answer: D
Rationale: The correct answer is D because in a patient with anemia and low hemoglobin concentration, their PaO2 will be decreased due to reduced oxygen-carrying capacity of blood. This is a result of decreased oxygen saturation in the blood. A: Decreased TPR is incorrect because anemia can lead to compensatory mechanisms such as increased sympathetic tone and vasoconstriction, resulting in increased total peripheral resistance. B: Increased cardiac output is incorrect as the heart may need to work harder to maintain oxygen delivery to tissues due to decreased oxygen-carrying capacity. C: Increased 2,3 DPG in RBC is incorrect because anemia can lead to decreased 2,3 DPG levels, which shift the oxygen-hemoglobin dissociation curve to the left, impairing oxygen release to tissues.
Question 2 of 5
Nurse Lei, caring for a client with a pneumothorax and who has had a chest tube inserted, continues gentle bubbling in the suction control chamber. What action is appropriate?
Correct Answer: A
Rationale: The correct answer is A: Do nothing, because this is an expected finding. When managing a client with a chest tube for a pneumothorax, gentle bubbling in the suction control chamber indicates that the system is functioning properly. This bubbling represents the movement of air and fluid out of the pleural space. It is important not to clamp the chest tube or increase suction pressure as this can lead to complications. Checking for an air leak is unnecessary in this scenario as continuous bubbling is an expected finding. Therefore, the appropriate action is to monitor the bubbling and ensure it remains gentle, as this signifies effective drainage.
Question 3 of 5
A male client is asking the nurse a question regarding the Mantoux test for tuberculosis. The nurse should base her response on the fact that the:
Correct Answer: B
Rationale: The correct answer is B. The Mantoux test for tuberculosis is a skin test that detects the presence of the tuberculosis bacteria in the body. It does not differentiate between active and dormant infection because it only measures the immune response to the infection. The presence of a wheal or area of redness at the injection site is a normal response to the test and does not indicate active tuberculosis. Measuring the area of redness in 3 days or requiring a second test in 3 months are not accurate statements about the Mantoux test. Therefore, the best response is B as it aligns with the purpose and limitations of the Mantoux test.
Question 4 of 5
A client diagnosed with pleurisy is being started on medication therapy with a nonsteroidal anti-inflammatory drug. A nurse teaches the client that this medication?
Correct Answer: D
Rationale: The correct answer is D because nonsteroidal anti-inflammatory drugs (NSAIDs) help relieve pain by reducing inflammation, which can improve breathing and coughing for a client with pleurisy. NSAIDs do not act as mild narcotic analgesics (B) or glucocorticoids (C). While NSAIDs may alleviate surface pain (A), their primary mechanism is reducing inflammation to relieve pain and improve respiratory function.
Question 5 of 5
A persistent, productive cough with bloody sputum (hemoptysis) is a common symptom of:
Correct Answer: D
Rationale: The correct answer is D: Tuberculosis. Hemoptysis is a hallmark symptom of tuberculosis due to the erosion of blood vessels in the lungs by the Mycobacterium tuberculosis bacteria. The persistent cough in tuberculosis is often productive and accompanied by bloody sputum. Emphysema (A) is characterized by shortness of breath and wheezing, not hemoptysis. Cystic fibrosis (B) presents with thick mucus production, not bloody sputum. Sinusitis (C) typically causes nasal congestion and facial pain, not hemoptysis.
