Number the following physiologic occurrences in the order they occur in the formation of urine.

Correct Answer: A

Rationale: Rationale: The correct order of physiologic occurrences in urine formation is as follows: A) Blood is filtered in the glomerulus. This is the initial step where blood enters the nephron for filtration. The other choices are incorrect because B) Reabsorption of water in the loop of Henle occurs after filtration, C) Reabsorption of electrolytes, glucose, amino acids, and small proteins in the tubules happens after the initial filtration, and D) Acid-base regulation in the distal tubule occurs after other processes such as reabsorption and secretion have taken place.

Correct Answer: C

Rationale: The correct answer is C. The most common cause of acute pyelonephritis from an ascending infection is a preexisting abnormality of the urinary tract. This abnormality can lead to urine stasis, making it easier for bacteria to ascend from the lower urinary tract to the kidneys. Choices A and B are incorrect because scarred kidneys and antibiotic resistance do not typically cause acute pyelonephritis. Choice D is incorrect as non-compliance with antibiotics may contribute to recurrent infections but is not the most common cause of pyelonephritis.

Correct Answer: D

Rationale: The correct answer is D because APSGN (Acute Poststreptococcal Glomerulonephritis) is caused by an immune response to a streptococcal infection. Therefore, the nurse must understand the pathophysiology, signs/symptoms, treatment, and potential complications associated with APSGN to provide effective care. Choice A, B, and C may not directly address the specific knowledge needed to care for a patient with APSGN, making them incorrect options.

Correct Answer: A

Rationale: The correct answer is A: Reflex incontinence. This type of incontinence occurs due to a lack of voluntary control over the bladder, usually resulting from a spinal cord lesion. In this case, the thoracic spinal cord lesion is causing the incontinence. The fact that incontinence occurs equally during the day and night suggests a lack of awareness or sensation of bladder fullness, characteristic of reflex incontinence. Summary of other choices: B: Overflow incontinence is due to bladder overdistension and is commonly associated with conditions like BPH or spinal cord injuries at the sacral level. C: Functional incontinence is when a person is unable to reach the toilet in time due to physical or cognitive impairments. D: Incontinence after trauma is a broad term and does not specifically address the pattern of incontinence described in the question.

Correct Answer: D

Rationale: The correct answer is D. Stomatitis in CKD patients is often caused by iron salts, calcium-containing phosphate binders, and limited fluid intake. Iron salts and calcium binders can lead to mucosal irritation in the GI tract, exacerbating stomatitis. Limited fluid intake can cause dehydration, leading to oral mucosal dryness and vulnerability to stomatitis. A: High serum sodium levels do not directly cause stomatitis in CKD patients. B: Irritation of the GI tract from creatinine is not a common cause of stomatitis in CKD patients. C: Increased ammonia from bacterial breakdown of urea is more related to hepatic encephalopathy rather than stomatitis in CKD patients.
