Correct Answer: C

Rationale: The correct answer is C: 12 to 18 g/100mL. Normal hemoglobin values typically range from 12 to 18 g/100mL in adults. This range reflects the normal concentration of hemoglobin in the blood and is commonly used as a reference range in clinical practice. Choices A, B, and D are incorrect because they do not fall within the typical normal range for hemoglobin levels. Choice A (38% to 48%) is a percentage range, not a direct measurement of hemoglobin concentration. Choice B (48 to 54 mg%) and Choice D (27 to 36 g/dL) are outside the normal range for hemoglobin levels in adults. Therefore, the most appropriate and accurate choice among the options provided is C (12 to 18 g/100mL) based on standard reference values for hemoglobin concentration in the blood.

Correct Answer: C

Rationale: The correct answer is C. Aling Maria is admitted for myxedema, which is severe hypothyroidism. Symptoms of hypothyroidism include lethargy, weight gain, slow speech, and decreased respiratory rate. Bradycardia, weight loss, heart failure, and diarrhea are not typical symptoms of myxedema. Tachycardia, constipation, and exopthalmus are more commonly associated with hyperthyroidism. Hypothermia, weight loss, and increased respiratory rate are not consistent with myxedema. Thus, choice C is the most appropriate initial assessment for Aling Maria.

Correct Answer: A

Rationale: The correct answer is A: Universal blood and body fluid precautions. This is recommended by the CDC to prevent the spread of HIV because the virus can be present in blood and certain body fluids. Universal precautions involve treating all blood and body fluids as potentially infectious. Incorrect choices: B: Body systems isolation - This is not specific to preventing the spread of HIV and is not recommended by the CDC. C: Laminar flow room during active infection - This is not a standard recommendation for preventing the spread of HIV. D: Needle and syringe precautions - While important in preventing needlestick injuries, it is not the primary method recommended by the CDC for preventing the spread of HIV.

Correct Answer: D

Rationale: The correct answer is D: Stapedectomy. This procedure is used to correct otosclerosis by removing the stapes bone and replacing it with a prosthetic device. This restores normal hearing by allowing sound waves to travel through the ear properly. Myringotomy (A) is a procedure to drain fluid from the middle ear, not to correct otosclerosis. Mastoidectomy (B) is the removal of infected mastoid air cells, not related to otosclerosis. Myringoplasty (C) is a surgical procedure to repair a perforated eardrum, not used for otosclerosis. Stapedectomy is the most appropriate choice for correcting otosclerosis as it directly addresses the abnormal bone growth in the middle ear.

Correct Answer: A

Rationale: Step-by-step rationale for why answer A is correct: 1. Safety: Morbidly obese patients are at higher risk of falls during transfers. 2. Assistance: Having two other personnel ensures safe transfer. 3. Weight distribution: Distributing the patient's weight among multiple helpers reduces strain. 4. Proper body mechanics: Allows for proper positioning and technique while assisting. Summary of why other choices are incorrect: B. Medication doesn't address the safety concern of transferring a morbidly obese patient. C. Reviewing activity orders is not the immediate action needed for the patient's first bathroom transfer. D. Offering a walker may not provide sufficient support for a morbidly obese patient during the transfer.
