Sagittal suture at the skull.

Correct Answer: A

Rationale: The sagittal suture runs from the front to the back of the skull, dividing it into left and right halves. This is its primary function, aligning with the midline of the skull. Choice A is correct because it accurately describes the anatomical division created by the sagittal suture. Choices B, C, and D are incorrect because they do not accurately represent the function of the sagittal suture.

Correct Answer: A

Rationale: The correct answer is A because standing position typically leads to increased pulse rate due to the body's response to the change in posture. When standing up, blood pools in the lower extremities, causing a temporary drop in blood pressure, which triggers the heart to beat faster to maintain adequate blood flow to the brain and other vital organs. This increase in pulse helps to counteract the drop in blood pressure and prevent dizziness or fainting. Summary: - Choice B (Decreased pulse) is incorrect because standing usually causes an increase in pulse rate. - Choices C and D are not applicable since they are blank.

Correct Answer: A

Rationale: The correct answer is A: Going to school. Children experience developmental stressors during their school years due to academic pressure, social challenges, and emotional changes. School environments can be demanding and unfamiliar, leading to stress and anxiety. Other choices like B (Going to job interviews) are typically not applicable to children as they are not in the workforce. Choices C and D are likely placeholders and do not relate to developmental stressors for children.

Correct Answer: A

Rationale: The correct answer is A: Give protein-rich foods. Proteins are essential for wound healing as they help in tissue repair and regeneration. They also play a crucial role in immune function, which is important in preventing infections in the wound site. Protein-rich foods provide the necessary building blocks for the body to heal properly. Choice B, providing vitamin C-rich foods, is not the best option as vitamin C primarily aids in collagen synthesis, which is important for skin health but not as directly involved in wound healing as proteins. Choices C and D are incomplete and do not provide any specific action related to wound healing.

Correct Answer: B

Rationale: The correct answer is B: 2-3 drops into the conjunctiva. This is correct because eye drops should be instilled directly onto the conjunctiva to ensure proper absorption and effectiveness of the medication. Dropping the medication directly onto the conjunctiva also minimizes the risk of contamination and allows for better distribution of the medication across the eye surface. Choices A, C, and D are incorrect as they do not specify the correct technique for administering eye drops and may result in inadequate delivery of the medication or potential harm to the eye.
