Correct Answer: C

Rationale: The correct answer is C. Ear cartilage folded over, lanugo present over much of the body, and slow recoil time are all characteristics of a preterm infant. A is incorrect because full sole creases, nails extending beyond the fingertips, and scarf sign showing the elbow beyond the midline are features of a term infant. B is incorrect as testes located in the upper scrotum, rugae covering the scrotum, and vernix covering the entire body are also indicative of a term infant. D is incorrect because a 1 cm breast bud, peeling skin and veins not visible, and rapid recoil of legs and arms to extension are characteristics seen in a more mature infant, not a preterm newborn.

Correct Answer: A

Rationale: Keeping the umbilical cord dry and exposed to air is the correct instruction because it promotes faster healing. Moisture can delay the healing process and increase the risk of infection. Cleaning the cord with alcohol at every diaper change or covering it with a sterile dressing can actually impede the healing process by preventing airflow. Submerging the cord in water during baths is not recommended as it can introduce moisture and increase the risk of infection.

Correct Answer: A

Rationale: To ensure an accurate gestational rating on the Ballard gestational assessment tool, healthcare professionals should document the amount and area of vernix coverage before drying the newborn. Drying the baby after birth could disturb the vernix, potentially affecting the gestational age assessment. Assessing and documenting the vernix coverage beforehand enables a more precise evaluation using the Ballard gestational assessment tool. Choices B, C, and D are incorrect as they are not directly related to gestational rating on the Ballard assessment tool.

Correct Answer: A

Rationale: The corrected response 'His head is molded from fitting through the birth canal. It will become more round.' is the best answer as it explains the physiological reason for the baby's appearance after birth. It reassures the father that the pointed and puffy-looking head is a normal part of the birthing process and will resolve on its own. Choice B is incorrect because while 'cone head' is a term used colloquially, it does not provide a detailed explanation. Choice C is incorrect and should be avoided as it introduces unnecessary worry by suggesting brain damage. Choice D is not an appropriate response as it doesn't address the father's concern or provide accurate information about newborn physiology.

Correct Answer: B

Rationale: Multivitamins are not typically considered a non-pharmacological technique for lowering blood pressure. While dietary changes, smoking cessation, and limiting caffeine intake can positively impact blood pressure levels, multivitamins are generally not specifically recommended as a primary intervention for this purpose. Dietary changes can include reducing salt intake and increasing potassium-rich foods, which are known to help manage blood pressure. Smoking cessation is crucial due to the negative impact of smoking on blood pressure and overall cardiovascular health. Limiting caffeine intake is advised as excessive caffeine consumption can lead to a temporary increase in blood pressure. Therefore, focusing on lifestyle modifications like healthy eating, smoking cessation, and caffeine reduction is more effective in managing blood pressure than relying on multivitamins.
