1. What are the fine, down-like hairs on the newborn's ears, shoulders, lower back, and/or forehead known as?

A. Vernix.
B. Lanugo.
C. Milia.
D. Vibrissae.

Correct answer: B

Rationale: Lanugo is the term used to describe the fine, down-like hairs found on a newborn's ears, shoulders, lower back, and/or forehead. These hairs are different from vernix, which is a waxy or cheese-like white substance covering the skin of newborns. Milia are small, white, or yellowish cysts that commonly appear on a newborn's face, while vibrissae are the thick, stiff hairs commonly found around the nose and other parts of the face.

2. The wound irrigation process cleanses the wound and:

A. Reduces the potential pain in the wound region or area.
B. Stops the spread of infection by creating a 'clean' area.
C. Pushes extravasated blood from a hematoma into nearby healthy tissue.
D. Allows for the introduction of medications in solution form.

Correct answer: D

Rationale: The correct answer is D because wound irrigation allows for the introduction of medications in solution form to the wound site. Choice A is incorrect because while wound irrigation can help with pain management indirectly by promoting healing, its primary purpose is not to reduce pain directly. Choice B is incorrect as wound irrigation primarily aims to cleanse the wound and remove contaminants rather than creating a 'clean' area to stop infection spread. Choice C is incorrect because wound irrigation does not involve pushing extravasated blood from a hematoma into nearby healthy tissue; its main goal is to cleanse the wound and promote healing.

3. Round off these numbers to the nearest tenth:

A. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
B. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
C. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
D. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7

Correct answer: B

Rationale: The correct answer is B. When rounding off to the nearest tenth, 1.027 becomes 1.0 because the digit in the hundredth's place is less than 5. For the other numbers, they are rounded correctly to the nearest tenth: 5.5778 = 5.6, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7. Therefore, option B is the most accurate in rounding off these numbers to the nearest tenth. Choices A, C, and D are incorrect as they do not round 1.027 to 1.0 as required when rounding to the nearest tenth.

4. A nurse at a long-term care facility is planning a fall prevention program for the residents. Which of the following interventions should the nurse include?

A. Apply vest restraints to residents who are confused
B. Keep all four side rails up on beds at night
C. Accompany residents over 85 years of age during ambulation
D. Implement rounds every 2 hours during the day to offer toileting

Correct answer: D

Rationale: The correct answer is to implement rounds every 2 hours during the day to offer toileting. This intervention helps prevent falls by addressing the common cause of unassisted mobility, which is the need to use the bathroom. Choice A is incorrect as restraints should not be the first choice for fall prevention due to the risk of injury and loss of independence. Choice B is incorrect because all side rails up can lead to entrapment and should only be used based on individualized assessments. Choice C may not be feasible for all residents over 85 years old and does not directly address the risk of falls.

5. What does the mnemonic PERLA stand for in the assessment of the eyes?

A. Pupils equally reactive to light and accommodation
B. Patient eyes are equally recessed and responsive to light and acuity
C. Patient eyes are equally responsive to light and acuity
D. Pupils equally reactive to light and acuity

Correct answer: A

Rationale: The correct answer is A: 'Pupils equally reactive to light and accommodation.' PERLA is a mnemonic used in eye assessments to check for Pupils being equally reactive to Light and Accommodation. Choice B is incorrect as it includes irrelevant information about the eyes being recessed. Choice C is incorrect as it is missing the mention of pupils and accommodation. Choice D is incorrect as it misses the mention of accommodation.
