Correct Answer: B

Rationale: Nurse Chona should explain to Patient Noel that the sign of negative before the word means that he is not drinking alcohol or smoking cigarettes. This is a simple misunderstanding and clarification should help clear up any confusion. It is important to uphold patient confidentiality and respect their autonomy, rather than reprimanding the patient for looking at their own chart. It is also essential to address any discrepancies in the patient's medical record to ensure accurate information is documented for proper treatment and care.

Correct Answer: A

Rationale: Nurse Nilda immediately responds to any cry from her pediatric patients to attend to her patients who cannot communicate verbally. Crying is one of the few ways infants and young children communicate their needs and discomforts. By responding promptly to their cries, Nurse Nilda can assess and address potential issues such as hunger, pain, discomfort, or other needs that the child may have. This enhances the quality of care provided and helps in comforting and soothing the child, ultimately promoting their well-being and building trust between the nurse and the patient.

Correct Answer: B

Rationale: The patient's presentation of well-demarcated, erythematous plaques with silvery scales on the trunk and extensor surfaces of the limbs is classic for psoriasis. Additionally, the family history of similar skin lesions further supports the diagnosis of psoriasis, as it is a condition with a genetic predisposition. Pityriasis rosea typically presents with a herald patch followed by oval, scaly lesions in a Christmas tree pattern. Erythema multiforme is characterized by target-like lesions. Lichen planus presents as purple, polygonal, flat-topped papules that may have fine white lines on their surface known as Wickham striae.

Correct Answer: A

Rationale: Neutrophils are a type of white blood cell that play a crucial role in immune defense against pathogens, particularly in phagocytosis - the process by which they engulf and destroy invading microorganisms. In a severe fungal infection, impaired neutrophil function would most likely affect their ability to effectively perform phagocytosis, leading to a compromised immune response against the fungal pathogen. This would result in increased susceptibility to the infection and potentially severe outcomes for the patient. Antibody production, cytokine secretion, and mast cell degranulation are important components of the immune response, but neutrophils are primarily responsible for phagocytosis in the innate immune system.

Correct Answer: A

Rationale: The presentation described with sudden-onset, painless vision loss, a cherry-red spot at the macula, and attenuated retinal vessels is classic for central retinal artery occlusion (CRAO). CRAO occurs when the central retinal artery, which supplies blood to the inner retinal layers, becomes occluded. The cherry-red spot is due to the exposure of the underlying choroid, which still appears red as it is not affected by the blockage. Attenuated retinal vessels and a pale retina may also be seen due to ischemia. In contrast, central retinal vein occlusion (choice B) presents with sudden painless vision loss, retinal hemorrhages, dilated retinal veins, and cotton-wool spots. Retinal detachment (choice C) typically presents with flashes, floaters, and a curtain-like shadow across the vision. Acute angle-closure glaucoma (
