A nurse is performing a cardiovascular assessment on a healthy client. In which of the following anatomical landmarks would the nurse expect to palpate the client's Point of Maximal Impulse (PMI)?
Left fourth intercostal space at the sternal border.
Left third intercostal space at the sternal border.
Left second intercostal space at the midclavicular line.
Left fifth intercostal space at the midclavicular line.
The Correct Answer is D
The correct answer is: d. Left fifth intercostal space at the midclavicular line.
Choice A: Left fourth intercostal space at the sternal border
The fourth intercostal space at the sternal border is not the typical location for the Point of Maximal Impulse (PMI). This area is more commonly associated with the tricuspid valve auscultation point. The PMI is usually found more laterally and inferiorly.
Choice B: Left third intercostal space at the sternal border
The third intercostal space at the sternal border is also not the correct location for the PMI. This area is generally used for auscultating the pulmonic valve. The PMI is located further down and towards the midclavicular line.
Choice C: Left second intercostal space at the midclavicular line
The second intercostal space at the midclavicular line is typically where the aortic valve is auscultated. The PMI is not found this high up on the chest.
Choice D: Left fifth intercostal space at the midclavicular line
This is the correct location for palpating the Point of Maximal Impulse (PMI). The PMI is usually located at the apex of the heart, which is found at the left fifth intercostal space along the midclavicular line. This is where the left ventricle is closest to the chest wall and can be felt most strongly during systole.

Correct Answer is D
Explanation
Choice A rationale:
Hypotension is not an expected manifestation of hypoxemia during an asthma attack. Hypotension refers to abnormally low blood pressure. During an asthma attack, the body's response to hypoxemia is more likely to involve increased heart rate (tachycardia) as the heart attempts to compensate for decreased oxygen levels.
Choice B rationale:
Dysphagia is not directly related to hypoxemia during an asthma attack. Dysphagia refers to difficulty swallowing, which is not a typical respiratory manifestation. Hypoxemia in asthma is more likely to lead to symptoms such as shortness of breath, wheezing, and increased work of breathing.
Choice C rationale:
Peripheral edema is not a typical manifestation of hypoxemia during an asthma attack. Peripheral edema, or swelling in the extremities, can occur in conditions like heart failure but is not directly related to the airway constriction and reduced oxygen exchange seen in asthma attacks.
Choice D rationale:
Agitation is the correct choice. Hypoxemia, which occurs when there is a decrease in the oxygen levels in the blood, can lead to inadequate oxygen supply to the brain. This can result in neurological symptoms such as agitation, restlessness, confusion, and even loss of consciousness. Agitation is a manifestation of the body's attempt to cope with the lack of oxygen.
Correct Answer is B
Explanation
Choice A rationale:
Applying the pulse oximeter probe to the toe is not the most appropriate location. While toe measurements can be used, the fingers are more commonly used due to their accessibility and accuracy. Edema in the hands could affect the accuracy of readings.
Choice B rationale:
The nurse should apply the pulse oximeter probe to the earlobe. This choice is correct because the earlobe is a well-vascularized and easily accessible area that provides accurate oxygen saturation measurements. Thickened toenails and edema of the hands might compromise readings in those locations.
Choice C rationale:
Applying the pulse oximeter probe to a skin fold is not a recommended site for oxygen saturation measurement. While there are various sites where pulse oximeters can be applied, the earlobe and finger are more suitable due to their consistent blood flow and accessibility.
Choice D rationale:
While applying the pulse oximeter probe to the finger is a common and acceptable practice, in this scenario, edema of the hands could affect the accuracy of the readings. The earlobe is a better choice as it is less likely to be affected by edema and can provide accurate readings.
