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.

Explanation
Choice A rationale:
Difficulty maintaining personal hygiene is not typically an early indication of mild Alzheimer's disease. In the early stages, individuals can still manage personal hygiene.
Choice B rationale:
Difficulty handling finances may occur in the later stages of Alzheimer's disease, but it is not an early indication. In the early stages, the person might still manage financial matters.
Choice C rationale:
Difficulty remembering the names of new friends is a common early sign of mild Alzheimer's disease. It reflects the impairment of short-term memory that often occurs in the early stages of the disease.
Choice D rationale:
Difficulty driving to and from familiar places is more likely to be a mid-to-late-stage symptom of Alzheimer's disease. In the early stages, individuals might still drive familiar routes with minimal difficulty.
Correct Answer is C
Explanation
Choice A rationale:
Increasing potassium consumption is unrelated to cephalexin, an antibiotic. It is not a necessary precaution or action to take while on this medication.
Choice B rationale:
Applying lotion to the skin to relieve itching is not related to cephalexin use. Itching is not a common side effect of this antibiotic, so the client's statement indicates a misunderstanding of the teaching.
Choice C rationale:
Avoiding sun exposure is essential while taking cephalexin because it is known to cause photosensitivity reactions. Sun exposure can lead to severe skin reactions, so the client's statement indicates an understanding of the teaching.
Choice D rationale:
Keeping the medication refrigerated is not necessary for cephalexin oral suspension. It should be stored at room temperature unless specified otherwise by the manufacturer. The client's statement suggests a misunderstanding of the medication storage instructions.
