1. What is the BEST blood collection location for a newborn?
- A. the AC
- B. the veins of the forehead
- C. the heel
- D. the fingertips
Correct answer: C
Rationale: When collecting blood from newborns, it is safest and most commonly done by collecting blood from the lateral or medial aspect of the baby's heel. This location is preferred due to the accessibility of the veins and the minimal discomfort caused to the newborn. Veins in the forehead are not commonly used for blood collection in newborns. The fingertips are not optimal for blood collection in newborns due to their small size and the potential for causing discomfort. The AC (antecubital) area, typically used in adults for blood collection, is not recommended for newborns due to the size of their veins and the potential risk of injury.
2. Which of the following is a fat-soluble vitamin?
- A. Vitamin C
- B. Vitamin D
- C. Vitamin B-6
- D. Riboflavin
Correct answer: B
Rationale: The correct answer is Vitamin D. Fat-soluble vitamins are those that can be stored in the body, allowing excess amounts to be stored for later use. While this storage ability can help prevent deficiencies, it also poses a risk of toxicity. The fat-soluble vitamins are A, E, D, and K. Choice A, Vitamin C, is water-soluble, not fat-soluble. Choice C, Vitamin B-6, and Choice D, Riboflavin, are also water-soluble vitamins and not fat-soluble.
3. When reviewing the demographics of ethnic groups in the United States, which group does the nurse recall as the largest and fastest-growing population?
- A. Asian
- B. Hispanic
- C. American Indian
- D. African American/Black
Correct answer: B
Rationale: The correct answer is 'Hispanic.' Hispanics are the largest and fastest-growing population in the United States. While African Americans/Blacks, Asians, American Indians, and other groups are significant, Hispanics currently represent the largest demographic group. African American/Black, Asian, and American Indian populations are substantial but not as large or fast-growing as the Hispanic population. Therefore, Hispanic is the most appropriate choice in this scenario.
4. Which of these actions illustrates the correct technique for a nurse when assessing oral temperature with a glass thermometer?
- A. Wait 30 minutes if the patient has ingested hot or iced liquids.
- B. Leave the thermometer in place for 3 to 4 minutes if the patient is afebrile.
- C. Shake the glass thermometer down to 35.5�C before taking the patient's temperature.
- D. Place the thermometer at the base of the tongue and ask the patient to close his or her lips.
Correct answer: B
Rationale: The correct technique for assessing oral temperature with a glass thermometer involves leaving the thermometer in place for 3 to 4 minutes if the patient is afebrile and up to 8 minutes if the patient is febrile. Waiting 30 minutes if the patient has ingested hot or iced liquids is incorrect; instead, the nurse should wait 15 minutes in such cases. Shaking the glass thermometer down to 35.5�C, not 37.5�C, is the correct procedure before taking the patient's temperature. Placing the thermometer at the base of the tongue, not the front, and asking the patient to close their lips is the proper way to position the thermometer. Therefore, the correct answer is to leave the thermometer in place for 3 to 4 minutes if the patient is afebrile and up to 8 minutes if the patient is febrile.
5. Which of the following statements best describes footdrop?
- A. The foot is permanently fixed in the dorsiflexion position
- B. The foot is permanently fixed in the plantar flexion position
- C. The toes of the foot are permanently fanned
- D. The heel of the foot is permanently rotated outward
Correct answer: B
Rationale: Footdrop results in the foot becoming permanently fixed in a plantar flexion position, not dorsiflexion. This position points the toes downward. The client may be unable to put weight on the foot, making ambulation difficult. Footdrop can be caused by immobility or chronic illnesses that cause muscle changes, such as multiple sclerosis or Parkinson's disease. Choice A is incorrect because footdrop leads to plantar flexion, not dorsiflexion. Choice C is incorrect as it describes a different condition known as 'toe fanning.' Choice D is incorrect as it describes an external rotation of the heel, which is not a characteristic of footdrop.
