Which is the most commonly used method in completed suicides?

Correct Answer: A

Rationale: Firearms are the most commonly used method in completed suicides, accounting for nearly 50% of all suicide deaths in the United States. Firearms are particularly lethal and result in a higher success rate compared to other methods. The quick and irreversible nature of firearm suicides contributes to their high prevalence. Additionally, the easy access to firearms in many households increases the likelihood of their use in suicide attempts.

Correct Answer: B

Rationale: Renal transplantation is considered the preferred means of renal replacement therapy in children with end-stage renal disease. This is because transplantation offers the best long-term outcomes and quality of life for children compared to other forms of renal replacement therapy such as dialysis. Children who undergo successful renal transplantation tend to have improved growth, development, and overall health compared to those who remain on dialysis. Transplantation can provide children with the opportunity to live a relatively normal and healthy life, making it the preferred treatment option in pediatric patients with end-stage renal disease.

Correct Answer: C

Rationale: Peripheral edema is a common clinical manifestation of systemic venous congestion that can occur with heart failure. In heart failure, the heart is unable to pump effectively, leading to a backup of blood in the veins. This increased pressure in the veins causes fluid to leak out into the surrounding tissues, resulting in swelling or edema, most commonly in the lower extremities. Tachypnea (rapid breathing) and tachycardia (fast heart rate) are more associated with the compensatory mechanisms of the body to try to maintain cardiac output and oxygenation. Pale, cool extremities are more indicative of poor peripheral perfusion, which can occur with severe heart failure but are not the typical manifestations of systemic venous congestion.

Correct Answer: D

Rationale: Rheumatic fever is an inflammatory disease that can develop after a streptococcal infection, such as strep throat. One of the most serious complications of rheumatic fever is cardiac involvement, specifically damage to the heart valves. This occurs due to the body's immune response attacking the heart valves as a result of molecular mimicry between streptococcal antigens and human tissues. The damage to the heart valves can result in conditions like mitral valve stenosis or regurgitation, which can lead to heart failure if not managed appropriately. Therefore, cardiac valve damage is a common and serious complication of rheumatic fever that requires monitoring and treatment to prevent long-term consequences.

Correct Answer: C

Rationale: The patient's symptoms of recent weight gain, 3+ pitting edema of his feet, distended neck veins, and crackles in his lungs are indicative of fluid volume excess. These signs and symptoms suggest that the patient is retaining too much fluid, leading to the edema and congestion in the lungs. The nursing diagnosis of Excess Fluid Volume is appropriate for this patient as it reflects the patient's current physiological state and guides the plan of care to address excess fluid accumulation through interventions such as diuretic therapy, fluid restriction, and monitoring of intake and output. Deficient fluid volume, Imbalanced nutrition more than body requirements, and Noncompliance are not appropriate nursing diagnoses given the patient's presentation of fluid overload.
