What statement is an advantage of peritoneal dialysis compared with hemodialysis?

Correct Answer: C

Rationale: Peritoneal dialysis is generally easier to learn and can be safely performed at home. Although dietary limitations still apply, this method offers greater flexibility in treatment scheduling compared to hemodialysis, which often requires multiple weekly visits to a dialysis center.

Correct Answer: B

Rationale: The weight loss is most likely due to the reduction of edema, as glomerulonephritis often causes fluid retention that resolves with treatment, leading to significant weight loss.

Correct Answer: A

Rationale: Cystitis is the medical term for inflammation of the bladder. Urethritis refers to inflammation of the urethra, urosepsis to a systemic infection stemming from the urinary tract, and bacteriuria to the presence of bacteria in the urine.

Correct Answer: D

Rationale: Infrequent voiding can lead to urinary stasis, which increases the risk of urinary tract infections by allowing bacteria to multiply in the bladder. Encouraging regular voiding and proper hydration can help prevent UTIs. Choices A, B, and C are incorrect. Excessive intake of carbonated beverages may irritate the bladder but is not a direct cause of UTIs. Insufficient water intake can concentrate urine but does not necessarily lead to infections. A voiding pattern of 5-6 times a day is within the normal range and is not associated with increased UTI risk.

Correct Answer: C

Rationale: Peritoneal dialysis is generally easier to learn and can be safely performed at home. Although dietary limitations still apply, this method offers greater flexibility in treatment scheduling compared to hemodialysis, which often requires multiple weekly visits to a dialysis center.

Correct Answer: D

Rationale: The correct answer is D. Asthma triggers cause bronchoconstriction, airway inflammation, and increased mucus production, leading to difficulty breathing. This combination of manifestations results in narrowing of the airways, making it hard for the individual to breathe effectively. Choices A, B, and C are incorrect because during an asthma attack, bronchodilation, muscle relaxation, and decreased mucus production do not occur. Instead, the airways constrict, become inflamed, and produce excess mucus, contributing to the breathing difficulties experienced by individuals with asthma.

Correct Answer: D

Rationale: The Absolute Neutrophil Count (ANC) is crucial for determining the child's ability to fight infections. Neutrophils play a key role in combating bacterial infections. Monitoring the ANC is essential before administering chemotherapy, as a low ANC indicates an increased risk of infection. Hemoglobin, red blood cell count, and platelets are important for assessing oxygen-carrying capacity, anemia, and clotting function, respectively, but they do not directly reflect the child's capability to fight infections.

Correct Answer: B

Rationale: The correct answer is B. Irregular respirations with periodic pauses are normal in a 1-month-old infant. Choice A is incorrect because the normal respiratory rate for an infant at this age is higher than the range provided. Choice C is incorrect as irregular respirations are expected in infants. Choice D is not appropriate as irregular respirations with periodic pauses are a normal finding in young infants and do not necessarily indicate a concern that requires immediate notification of the healthcare provider.

Correct Answer: A

Rationale: Renal ultrasonography provides imaging of the renal parenchyma and pelvis without the risks associated with radiation or radioactive isotopes, making it a safer option, especially for children.
