1. 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.

2. What is the minimum amount of personal protective equipment for a nurse when working with a newborn immediately after a high-risk delivery in a client's room?

A. Sterile gown, gloves
B. Mask, gown, shoe covers
C. Gloves
D. Hat, mask, gloves, gown, shoe covers

Correct answer: C

Rationale: The correct answer is gloves. When attending a high-risk delivery and handling a newborn immediately after birth, the minimum personal protective equipment required for a nurse includes gloves. This is essential to protect the nurse from potential exposure to the mother's blood or body fluids that may be present on the newborn's skin. Choices A, B, and D include additional protective equipment that is not necessary for this specific scenario. Wearing gloves is crucial for infection control and to prevent the transmission of pathogens.

3. The nurse is preparing to assess a patient’s abdomen by palpation. How should the nurse proceed?

A. Avoid palpating reportedly “tender” areas as this may cause pain.
B. Palpate tender areas quickly to minimize patient discomfort.
C. Initiate the assessment with deep palpation while encouraging the patient to relax and take deep breaths.
D. Begin the assessment with light palpation to detect surface characteristics and to acclimate the patient to touch.

Correct answer: D

Rationale: The correct approach is to begin the assessment with light palpation to detect surface characteristics and to acclimate the patient to touch. This allows the nurse to first assess surface features before proceeding to deeper palpation. Starting with light palpation also helps the patient become more comfortable with being touched, creating a smoother examination experience. Palpating tender areas quickly, as suggested in choice B, can increase patient discomfort. Deep palpation, as in choice C, is typically performed after light palpation to avoid discomfort and ensure proper assessment. Avoiding palpation of tender areas first, as in choice A, helps prevent causing unnecessary pain and should be done towards the end of the assessment.

4. When assessing a pulse, what should be noted?

A. Rate
B. Rate and quality
C. Rate, quality, and fullness
D. Rate, quality, fullness, and regularity

Correct answer: C

Rationale: When assessing a pulse, it is important to note the rate (number of beats per minute), quality (regular or irregular), and fullness (thread and weak or full and bounding). These aspects provide crucial information about the patient's cardiovascular status. Regularity, as mentioned in option D, is not typically assessed during a pulse check and is not necessary for routine pulse assessment. Choice A is too limited as it overlooks important aspects beyond just the rate. Choice B improves by adding quality but still lacks the fullness aspect. Choice C is the most comprehensive and accurate as it includes all three essential aspects for a thorough pulse assessment.

5. Which technique is correct when assessing the radial pulse of a patient?

A. Palpate for 1 minute if the rhythm is irregular.
B. Palpate for 15 seconds and multiply by 4 if the rhythm is regular.
C. Palpate for 2 full minutes to detect any variation in amplitude.
D. Palpate for 10 seconds and multiply by 6 if the rhythm is regular and the patient has no history of cardiac abnormalities.

Correct answer: A

Rationale: When assessing the radial pulse, if the rhythm is irregular, the pulse should be counted for a full minute to get an accurate representation of the pulse rate. In cases where the rhythm is regular, the recommended technique is to palpate for 15 seconds and then multiply by 4 to calculate the beats per minute. This method is more accurate and efficient for normal or rapid heart rates. Palpating for 30 seconds and multiplying by 2 is not as effective, as any error in counting results in a larger discrepancy in the calculated heart rate. Palpating for 2 full minutes is excessive and not necessary for routine pulse assessment. Palpating for 10 seconds and multiplying by 6 is not a standard technique and may lead to inaccuracies, especially in patients with cardiac abnormalities.
