Correct Answer: D

Rationale: Creatinine clearance is a diagnostic test that helps determine both the glomerular filtration rate (GFR) and the extent of glomerular damage in the renal system. Creatinine is a waste product produced by muscles and excreted by the kidneys. A decrease in the glomerular filtration rate indicates impaired kidney function, which could be due to glomerular damage or other renal issues. By measuring the amount of creatinine in the blood and urine over a specific period of time, creatinine clearance provides an estimate of the GFR. This test is commonly used to assess kidney function in patients with renal disease or renal impairment.

Correct Answer: B

Rationale: B. Check with your healthcare provider before taking herbal remedies: It is important to consult with a healthcare provider before taking any herbal remedies while on aspirin therapy. Herbal remedies can potentially interact with aspirin and affect its efficacy or increase the risk of side effects.

Correct Answer: B

Rationale: In a client with left-sided heart failure, lying on the left side can help reduce the workload on the heart by promoting better venous return and reducing preload. This position can help decrease the amount of blood in the pulmonary circulation and improve cardiac output. Placing one pillow under the head can provide comfort and proper alignment of the airway, allowing for easier breathing. It is important to avoid excessive elevation of the head as it could increase pressure on the heart and impede circulatory function. This position can also help prevent complications such as pulmonary congestion and fluid accumulation in the lungs.

Correct Answer: C

Rationale: An increased amount of glucocorticoids being released can lead to an inhibition of the immune response. Glucocorticoids have anti-inflammatory effects and suppress the immune system, which can make the patient more susceptible to infections and impair the body's ability to fight off pathogens. This can manifest as an increased risk of infections and slower wound healing in the patient with adrenal cortex dysfunction. The other options, such as delayed onset of puberty, decreased metabolic rate, and increased response to glucagon, are not directly related to the effects of increased glucocorticoids on the immune response.

Correct Answer: A

Rationale: Acute postinfectious glomerulonephritis is commonly associated with a preceding streptococcal infection, particularly strep throat. This inflammatory condition affects the glomeruli in the kidneys and can result in symptoms such as hematuria, proteinuria, hypertension, and edema. Therefore, asking the patient about recent strep throat can help establish a potential link to the development of acute postinfectious glomerulonephritis.
