Foundations and Adult Health Nursing Study Guide Answers

Correct Answer: B

Rationale: CPAP therapy is considered the gold standard treatment for obstructive sleep apnea (OSA) and is the most appropriate intervention for managing OSA and improving symptoms. CPAP therapy involves using a machine that delivers a continuous flow of air through a mask worn over the nose or mouth during sleep. This air pressure helps keep the airway open, preventing the collapse that causes apneas and snoring during sleep.

Correct Answer: B

Rationale: The primary aim of this law is to regulate the practice of professional nursing within the country. By establishing regulations, standards, and guidelines for nursing practice, the law ensures that nurses provide safe and competent care to patients. It also sets forth licensing requirements, scope of practice, and ethical standards to maintain quality and consistency in nursing care delivery. While enhancing the competence of professional nurses, facilitating mobility of nurses, and promoting the well-being of health workers may be important secondary goals, the main focus of the law is to regulate and govern the practice of nursing within the country.

Correct Answer: B

Rationale: The correct information about the nature of dengue fever that the nurse should relay to the community is that it could be deadly but preventable. Dengue fever is a viral infection spread by mosquitoes, particularly the Aedes aegypti mosquito. While many cases of dengue fever are mild, it can also lead to severe dengue, which can be life-threatening if not properly managed. However, preventive measures such as using mosquito repellent, wearing protective clothing, and eliminating breeding sites for mosquitoes can significantly reduce the risk of contracting dengue fever. Therefore, it is important for the community to be aware that while dengue fever can be deadly, it is also preventable with appropriate measures.

Correct Answer: A

Rationale: The patient's symptoms of fever, chills, headache, and myalgia after returning from sub-Saharan Africa are consistent with malaria. Intraerythrocytic ring forms and trophozoites observed on blood smear examination are characteristic of Plasmodium species, particularly Plasmodium falciparum, which is the most common and deadliest species causing malaria in sub-Saharan Africa. Plasmodium falciparum can lead to severe complications, such as cerebral malaria, if not promptly treated. Trypanosoma cruzi causes Chagas disease, not malaria. Borrelia burgdorferi is responsible for Lyme disease, which typically presents with a different set of symptoms like erythema migrans rash. Leishmania donovani causes visceral leishmaniasis, not malaria.

Correct Answer: D

Rationale: The constellation of symptoms presented (periorbital edema, hypertension, proteinuria) along with the laboratory findings (elevated creatinine and urea levels, hyperkalemia, metabolic acidosis) are classical signs of chronic kidney disease (CKD). In CKD, the kidneys gradually lose their function over time, leading to impaired filtration of waste products and electrolyte imbalance. The presence of hypertension and proteinuria are common in CKD due to the compromised renal function. Additionally, elevated serum creatinine and urea levels, hyperkalemia, and metabolic acidosis are indicative of kidney dysfunction.
