A nurse is caring for a client who develops a sudden onset of dyspnea. Which of the following findings should the nurse expect if the client has a pulmonary embolus?
Expiratory rhonchi.
Petechiae over the lower extremities.
Hemoptysis.
Flattened neck veins.
The Correct Answer is C
Choice A rationale:
Expiratory rhonchi are typically associated with conditions such as chronic bronchitis or asthma but are not specific to pulmonary embolism.
Choice B rationale:
Petechiae over the lower extremities is not a characteristic finding in pulmonary embolism. Petechiae are tiny red or purple spots that appear due to bleeding under the skin and may be associated with other conditions like thrombocytopenia.
Choice C rationale:
The correct choice. Hemoptysis, which refers to coughing up blood, is a concerning finding in pulmonary embolism. It occurs due to the obstruction of blood flow in the pulmonary vasculature, leading to blood leaking into the lungs.
Choice D rationale:
Flattened neck veins are more likely to be observed in conditions associated with decreased venous return to the heart, such as hypovolemia or cardiac tamponade, and are not directly related to pulmonary embolism.

Correct Answer is ["B","D"]
Explanation
Choice A rationale:
Lurasidone does not necessarily need to be taken on an empty stomach. It can be taken with or without food.
Choice B rationale:
Avoiding grapefruit juice is essential with lurasidone as it can interfere with the drug's metabolism and increase the risk of side effects.
Choice C rationale:
Changing positions slowly is relevant for medications that can cause orthostatic hypotension, but lurasidone is not typically associated with this side effect.
Choice D rationale:
Lurasidone can cause insomnia in some individuals, so it is important for the client to be aware of this potential side effect. It is best taken in the evening to minimize this effect.
Choice E rationale:
While involuntary movements (extrapyramidal symptoms) can occur with some antipsychotic medications, lurasidone has a lower risk of causing these side effects compared to older antipsychotics. It is not a major concern with lurasidone treatment.
Correct Answer is D
Explanation
Choice A rationale:
A PaO2 value of 86 mm Hg is within the normal range (80-100 mm Hg) and does not indicate respiratory acidosis. PaO2 measures the partial pressure of oxygen in arterial blood.
Choice B rationale:
A pH of 7.4 is within the normal range (7.35-7.45) and does not indicate respiratory acidosis. The pH reflects the acidity or alkalinity of the blood.
Choice C rationale:
An HCO3 (bicarbonate) level of 16 mEq/L is within the normal range (22-28 mEq/L) and does not indicate respiratory acidosis. HCO3 is a measure of the metabolic component of the body's acid-base balance.
Choice D rationale:
This is the correct choice. A PaCO2 value of 58 mm Hg is elevated and indicates respiratory acidosis. PaCO2 measures the partial pressure of carbon dioxide in arterial blood, and an elevated value suggests the presence of excess carbon dioxide, leading to acidosis.
