Adult Health Nursing First Chapter Quizlet

Correct Answer: A

Rationale: Pneumothorax is a condition characterized by the presence of air in the pleural space surrounding the lungs, which can lead to lung collapse. The nurse's assessment findings in a patient with pneumothorax are typically as follows:

Correct Answer: A

Rationale: The most likely causative agent in this scenario is Plasmodium falciparum, a protozoan parasite that causes malaria. The patient's symptoms of fever, chills, headache, and myalgia align with the typical presentation of malaria. Additionally, the presence of intraerythrocytic ring forms and trophozoites on blood smear examination is characteristic of Plasmodium species, particularly P. falciparum, which causes the most severe form of malaria.

Correct Answer: B

Rationale: Periodontitis is the dental condition characterized by inflammation of the gingival tissues surrounding the teeth. It is typically caused by poor oral hygiene practices, leading to plaque buildup and eventually gum disease. If left untreated, periodontitis can cause serious damage to the gum tissue and the underlying bones supporting the teeth, which can eventually result in tooth loss. Regular dental check-ups, proper oral hygiene habits, and professional cleanings are important for preventing and managing periodontitis.

Correct Answer: D

Rationale: A subarachnoid hemorrhage is characterized by bleeding within the subarachnoid space, the area between the arachnoid mater and the pia mater surrounding the brain. Patients typically present with a sudden-onset severe headache, altered mental status, and focal neurological deficits due to the mass effect of the blood in the subarachnoid space. Imaging, such as a CT scan, can confirm the presence of the hemorrhagic lesion. Ischemic stroke results from a blockage in the blood vessels supplying the brain, leading to tissue infarction and neurological deficits. Subdural hematoma is a collection of blood between the dura mater and the arachnoid mater, commonly seen following head trauma. Intracerebral hemorrhage involves bleeding within the brain tissue itself, often leading to focal neurological deficits.

Correct Answer: C

Rationale: When a nurse discovers a discrepancy between the medication order and the patient's medication record, the priority action is to verify the medication order with the prescriber to ensure accuracy and patient safety. Administering the medication without clarification can put the patient at risk. Documenting the discrepancy and informing the charge nurse is important, but it should not delay verifying the order with the prescriber. Contacting the pharmacy for clarification may be necessary in some cases, but the immediate action should be to confirm the prescription with the prescriber to prevent errors and ensure the patient receives the correct medication.
