What special consideration should be taken into account when Mario prepares Richard for postural drainage and percussion?

Correct Answer: A

Rationale: The correct answer is A, 'Monitoring a respiratory rate of 16 to 20 per minute'. When performing postural drainage and percussion, it is crucial to monitor the respiratory rate to ensure the safety and effectiveness of the procedure. Choice B, 'Assessing the client's ability to tolerate sitting and lying positions', while important, is not directly related to the specifics of postural drainage and percussion. Similarly, option C, 'Ensuring the client is free of signs of infection', although important, is not directly linked to the procedure. Option D, 'Knowing the time of the client's last food and fluid intake', might be relevant for other procedures, but it is not the primary consideration for postural drainage and percussion.

Correct Answer: D

Rationale: A pulse oximeter is used to detect the oxygen saturation levels in arterial blood before the onset of hypoxemia symptoms. This device provides essential information about the effectiveness of oxygen transportation to the body's tissues. Choice A is incorrect because a pulse oximeter does not directly measure hemoglobin levels nor determine the need for a blood transfusion. Choice B is incorrect because a pulse oximeter is designed specifically to assess oxygen saturation, not tissue perfusion. Choice C is incorrect because a pulse oximeter is not used to measure the efficacy of anti-hypertensive medications, but rather to monitor oxygen levels in the blood.

Correct Answer: D

Rationale: When measuring blood pressure, the cuff should be inflated to 30 mmHg above the estimated systolic blood pressure based on palpation of the radial or brachial artery. This ensures an accurate blood pressure measurement. Choices A, B, and C are incorrect. Deflating the cuff fully before starting a second reading (Choice A) does not directly relate to the position of the cuff during a reading. Deflating the cuff quickly after inflating to 180 mmHg (Choice B) is not recommended because it can potentially lead to inaccurate readings. While ensuring the cuff is large enough to wrap around the upper arm positioned 1 cm above the brachial artery is important (Choice C), this alone does not guarantee an accurate blood pressure reading. The correct inflation based on palpation is the key element for accuracy, which is why Choice D is correct.

Correct Answer: A

Rationale: The correct location to auscultate the apex beat is at the fifth intercostal space, along the midclavicular line. This is where the apical impulse, also known as the point of maximal impulse (PMI), can be best heard. Choices B, C, and D are incorrect anatomical locations for auscultating the apex beat, which makes them incorrect choices. Auscultating at the correct location allows healthcare providers to assess the heart's function and detect any abnormalities in heart sounds, which is crucial for comprehensive patient care.

Correct Answer: D

Rationale: The correct answer is 'Develop methods for data collection' (Choice D). In the nursing research process, after the research problem has been identified, the next step would typically be to develop methods for how data will be collected. This is essential to effectively address the research problem. 'Review related literature' (Choice A), while an important step, usually occurs after the research problem has been identified and before methods for data collection are developed. 'Seek permission from the hospital administrator' (Choice B) might be necessary at some point in certain situations, but it is not the immediate next step in the research process. 'Identify the research problem' (Choice C) would typically come before developing methods for data collection. Therefore, according to the typical sequence of steps in the nursing research process, Choice D is correct.
