Correct Answer: D

Rationale: The correct answer is D. Removing the mobile when the baby starts to push up prevents choking hazards as infants can reach and grab objects posing a risk of choking. Choice A is unsafe as setting the water heater at 130°F can scald a child. Choice B is incorrect because even when a baby can sit up, they still require close supervision in the bathtub. Choice C is unsafe as current guidelines recommend placing babies on their backs to sleep to reduce the risk of sudden infant death syndrome (SIDS). Therefore, choices A, B, and C are incorrect or unsafe practices for infant care.

Correct Answer: D

Rationale: Neuroblastoma, a common solid tumor in children, often presents with symptoms related to the mass effect it causes. Abdominal mass and weakness are classic signs of neuroblastoma due to the tumor originating in the adrenal glands near the kidneys and potentially compressing nearby structures. Lymphedema and nerve palsy (Choice A) are not typically associated with neuroblastoma. Hearing loss and ataxia (Choice B) are more common in conditions affecting the central nervous system rather than neuroblastoma. Headaches and vomiting (Choice C) are nonspecific symptoms and are less commonly linked to neuroblastoma compared to the characteristic abdominal findings.

Correct Answer: C

Rationale: The correct answer is C. Clients with COPD should limit alcohol intake, not just to weekends, to effectively manage their condition. Excessive alcohol consumption can worsen respiratory symptoms and interfere with medications. Choices A, B, and D are all appropriate and beneficial for clients with COPD. Salt intake reduction helps in managing fluid retention and blood pressure. Regular exercise improves lung function and overall health. Monitoring blood pressure is crucial for individuals with COPD as hypertension is a common comorbidity.

Correct Answer: B

Rationale: The correct answer is B: Mitral stenosis. A high-pitched scratching sound heard during both systole and diastole with the diaphragm of the stethoscope positioned at the left sternal border indicates mitral stenosis, not a pericardial friction rub. Pericardial friction rub is a to-and-fro, grating, or scratching sound due to inflamed pericardial surfaces rubbing together, typically heard in early diastole and late systole. Aortic regurgitation and tricuspid stenosis would present with different auscultatory findings compared to the described scenario, making them incorrect choices in this context.

Correct Answer: A

Rationale: When assessing pain quality, asking if the pain is sharp or dull helps determine the nature of the pain. Sharp pain is often associated with acute conditions, while dull pain may indicate a chronic issue. Choices B, C, and D are incorrect as they do not directly address the quality of the pain in terms of sharpness or dullness.
