The nurse keeps in mind that a thorough skin assessment is extremely important because the skin holds information about a person's:

Correct Answer: B

Rationale: The correct answer is B: Circulatory status. A thorough skin assessment is important as the skin provides valuable information on blood flow, oxygenation, and perfusion. Changes in skin color, temperature, and integrity can indicate circulatory issues like poor perfusion or compromised circulation. Understanding the circulatory status is crucial for identifying potential health problems and providing appropriate interventions. The other choices (A, C, D) are incorrect as they do not directly correlate with the primary purpose of a skin assessment, which is to evaluate the health of the circulatory system.

Correct Answer: B

Rationale: The correct answer is B: Rubella can damage the infant's organ of Corti, which will impair hearing. Rubella virus can cross the placenta and infect the developing fetus, leading to congenital rubella syndrome. This syndrome can cause damage to various organs including the organ of Corti in the inner ear, leading to hearing impairment. This occurs mainly when the infection happens during the first trimester when the organ systems are developing. Incorrect choices: A: Rubella may affect the mother's hearing but not the infant's - This is incorrect as rubella can indeed affect the infant's hearing through congenital rubella syndrome. C: Rubella is only dangerous to the infant in the second trimester of pregnancy - This is incorrect as rubella can harm the infant's hearing in the first trimester as well. D: Rubella can impair the development of CN VIII and thus affect hearing - While rubella can affect hearing, it primarily does so by damaging the organ of Corti

Correct Answer: B

Rationale: The correct answer is B: Hypomobility. In otitis media, there is an accumulation of fluid in the middle ear, which can lead to decreased mobility of the tympanic membrane. This can be observed during pneumatic otoscopy when the tympanic membrane does not move normally in response to insufflation. Choices A, C, and D are incorrect. A) A red and bulging tympanic membrane is more indicative of acute otitis media. C) Retraction with landmarks clearly visible is a sign of negative pressure in the middle ear, possibly indicating eustachian tube dysfunction. D) A flat, slightly pulled in at the center, and moves with insufflation is characteristic of a normal tympanic membrane.

Correct Answer: B

Rationale: The correct answer is B: Recognize that this situation requires immediate intervention. If the nurse is unable to suction the nares and pass a catheter through, it suggests a potential blockage or obstruction in the nasal passages, which could lead to respiratory distress. Immediate intervention is crucial to ensure the newborn's airway is clear and breathing is not compromised. Contacting the physician or seeking further medical assistance promptly is necessary to address the issue. Choice A is incorrect because simply attempting to suction again may not resolve the underlying obstruction, and delaying necessary intervention could be harmful. Choice C is incorrect as scheduling an appointment for the infant at a later time is not appropriate when immediate intervention is required. Choice D is not applicable as it does not provide any solution or guidance for the current situation.

Correct Answer: C

Rationale: Step 1: Understand the costal angle is the angle formed by the ribcage at the sternum. Step 2: A costal angle of approximately 90 degrees is within the normal range (normal is 90-120 degrees). Step 3: This angle allows for proper expansion of the lungs during breathing. Step 4: Choices A, B, and D are incorrect as they describe conditions or characteristics that are not associated with a normal costal angle. Summary: Option C is correct because a costal angle of approximately 90 degrees is a normal finding in a healthy adult, allowing for proper respiratory function.
