What are the early signs of heart failure in a patient?

Correct Answer: A

Rationale: The correct answer is A: Shortness of breath and weight gain. Early signs of heart failure typically manifest as shortness of breath due to fluid accumulation in the lungs and weight gain due to fluid retention in the body. Choices B, C, and D are incorrect. Fatigue and chest pain are symptoms commonly associated with heart conditions but are not specific early signs of heart failure. Nausea and vomiting are not typically early signs of heart failure. Cough can be a symptom of heart failure, but it is usually associated with other symptoms like shortness of breath rather than being an isolated early sign. Elevated blood pressure is not an early sign of heart failure; in fact, heart failure is more commonly associated with low blood pressure.

Correct Answer: D

Rationale: The correct answer is D: Non-maleficence. Non-maleficence refers to the ethical principle of avoiding harm. In this scenario, the nurse questions the medication prescription to prevent potential harm to the client, demonstrating the principle of non-maleficence. Choice A, fidelity, pertains to being faithful and keeping promises, which is not the focus of the scenario. Choice B, autonomy, relates to respecting a client's right to make decisions about their care, not the nurse's actions. Choice C, justice, involves fairness and equal treatment, which is not directly applicable to the nurse questioning a medication prescription to prevent harm.

Correct Answer: B

Rationale: Limiting the intake of phosphorus-rich foods is appropriate for a client with chronic kidney disease. In individuals with chronic kidney disease, the kidneys cannot filter phosphorus effectively, leading to a buildup in the blood. This can result in bone and heart problems. Therefore, reducing phosphorus intake is crucial to prevent complications. Choices A, C, and D are incorrect. Increasing potassium intake may be harmful as potassium levels can accumulate in the blood with impaired kidney function. Encouraging protein-rich foods may not be suitable as excessive protein intake can strain the kidneys. Advising to increase fluid intake should be done cautiously as individuals with chronic kidney disease may need to restrict fluids based on their stage of the disease.

Correct Answer: D

Rationale: The correct answer is D because having family members wear a gown and gloves when visiting clients with C. difficile is crucial to prevent the transmission of the infection. Options A, B, and C are incorrect because assigning the client to a room with a negative air-flow system, using alcohol-based hand sanitizer, and cleaning contaminated surfaces with a phenol solution are not specific measures for preventing the spread of C. difficile.

Correct Answer: A

Rationale: Corrected Rationale: The correct answer is immobility and poor nutrition. Immobility can lead to constant pressure on certain areas of the body, while poor nutrition can impair tissue repair and regeneration, both contributing to the development of pressure ulcers. Choices B, C, and D are incorrect because while obesity, diabetes, dehydration, malnutrition, use of assistive devices, and prolonged bedrest can impact skin integrity and wound healing, they are not the primary risk factors specifically associated with pressure ulcer development.

Correct Answer: A

Rationale: The correct answer is A. Administering glucose or dextrose is a crucial nursing intervention for a patient experiencing hypoglycemia as it helps to quickly raise blood sugar levels. Monitoring blood sugar levels is essential to ensure that the patient's glucose levels normalize. Choice B is incorrect because providing a high-carbohydrate snack may not be sufficient to rapidly raise blood sugar levels in severe hypoglycemia. Choice C is incorrect because while monitoring for sweating and confusion is important in hypoglycemia, it is not a direct nursing intervention. Choice D is incorrect as providing insulin would lower blood sugar levels further, worsening hypoglycemia.

Correct Answer: D

Rationale: The correct answer is to keep the cord stump dry until it falls off. This is important to promote natural healing and prevent infection. Choice A is incorrect because cleaning the cord with hydrogen peroxide daily can actually delay healing and increase the risk of infection. Choice B is incorrect as the cord stump typically falls off within 1 to 3 weeks, not in 5 days. Choice C is incorrect because a cord stump turning black is a normal part of the healing process and does not necessarily indicate a problem requiring immediate provider contact.

Correct Answer: C

Rationale: The correct answer is 0.9% sodium chloride. This solution is isotonic and helps maintain electrolyte balance during irrigation, preventing fluid and electrolyte imbalances. Tap water (choice A) may cause electrolyte imbalances due to its hypotonic nature. Sterile water (choice B) is hypotonic and can lead to electrolyte disturbances. 0.45% sodium chloride (choice D) is hypotonic and may also disrupt electrolyte balance when used for irrigation.

Correct Answer: A

Rationale: The correct answer is A: 'Heart disease and stroke.' Untreated hypertension can lead to various complications, including heart disease and stroke. These are common outcomes of long-term high blood pressure. Choice B, 'Kidney failure and vision loss,' is incorrect as kidney failure and vision loss are more commonly associated with diabetic complications rather than untreated hypertension. Choice C, 'Pulmonary embolism and arrhythmias,' while serious, are not among the primary complications of untreated hypertension. Choice D, 'Blood clots and gastrointestinal bleeding,' are not typical complications of untreated hypertension but can occur due to other conditions such as blood clotting disorders or gastrointestinal diseases.
