The nurse is performing the Denver II screening test on a 12-month-old infant during a routine well-child visit. The nurse should tell the infant's parents that the Denver II:

Correct Answer: C

Rationale: The correct answer is C because the Denver II screening test is indeed a tool designed to detect children who are slow in development across various areas, such as motor skills, social skills, and language development. It is not specific to intellectual ability or predicting future school problems, as suggested in option D. It also does not solely focus on speech disorders, as mentioned in option B. While the Denver II assesses cognitive, physical, and psychological development, it is primarily used to identify developmental delays rather than diagnosing specific disorders, making option A incorrect.

Correct Answer: C

Rationale: The correct answer is C: Washing hands before and after contact with patients. Hand hygiene is the most crucial step to prevent microorganism transmission in hospitals. It helps reduce the spread of infections from patient to patient and healthcare workers. Washing hands effectively removes bacteria and viruses, preventing their transmission. Wearing protective eyewear (A) is important for eye protection but does not directly prevent microorganism transmission. Wearing gloves (B) is essential for specific patient interactions but does not address all instances of transmission. Cleaning stethoscopes (D) is important for equipment hygiene, but handwashing is more critical for overall infection control.

Correct Answer: A

Rationale: The correct answer is A because observing the patient's body stature and nutritional status is a key component of the general survey, which involves assessing the overall appearance and health status of the patient. This step provides valuable information about the patient's overall well-being and can help identify any potential health issues. Choice B is incorrect because interpreting subjective information reported by the patient is part of the health history, not the general survey. Choice C is incorrect because measuring vital signs (temperature, pulse, respirations, and blood pressure) is part of the physical assessment, not the general survey. Choice D is incorrect because observing specific body systems while performing the physical assessment is also not part of the general survey, but rather a focused assessment on particular body systems.

Correct Answer: C

Rationale: Rationale: Choice C is correct because the force of a pulse is a reflection of the heart's stroke volume. The pulse strength is directly proportional to the volume of blood ejected by the heart with each beat. This means that a strong pulse indicates a larger stroke volume, while a weak pulse indicates a smaller stroke volume. Choices A, B, and D are incorrect because pulse strength is not typically recorded on a 0- to 2-point scale, does not directly demonstrate elasticity of the vessel wall, and is not solely a reflection of blood volume in the arteries during diastole.

Correct Answer: C

Rationale: The correct answer is C: Systolic blood pressure may be falsely low. An auscultatory gap is a silent interval between the Korotkoff sounds during blood pressure measurement, commonly seen in hypertension. If the nurse does not check for an auscultatory gap, they may miss this silent interval, leading to an underestimation of the systolic blood pressure. Choices A and B are incorrect because missing an auscultatory gap does not affect the ability to hear diastolic blood pressure or result in a falsely low diastolic reading. Choice D is incorrect as missing an auscultatory gap would not lead to a falsely high systolic blood pressure.
