1. What is the threshold of dextrose concentrations that can safely be administered through a peripheral IV?

• A. Dextrose concentrations below 20% can be safely administered through a peripheral IV; dextrose concentrations above 20% should not be administered through a peripheral IV.
• B. Dextrose concentrations below 5% can be safely administered through a peripheral IV; dextrose concentrations above 5% should not be administered through a peripheral IV.
• C. Dextrose concentrations below 10% can be safely administered through a peripheral IV; dextrose concentrations above 10% should not be administered through a peripheral IV.
• D. Dextrose concentrations above 5% can be safely administered through a peripheral IV; dextrose concentrations below 5% should not be administered through a peripheral IV.

Correct answer: C

Rationale: Dextrose concentrations below 10% are considered safe for administration through a peripheral IV, as concentrations above this threshold can lead to phlebitis, causing inflammation of the vein. Concentrations above 10% should not be administered through a peripheral IV to prevent vein irritation. Choice A is incorrect because concentrations above 20% are too high for a peripheral IV. Choice B is incorrect as dextrose concentrations below 5% are too low to be effective. Choice D is incorrect because the statement is reversed, suggesting that concentrations above 5% are safe, which is not true.

2. A multigravida pregnant woman asks the nurse when she will start to feel fetal movements. Around which week of gestation does the nurse tell the mother that fetal movements are first noticed?

• A. 16 weeks
• B. 6 weeks
• C. 8 weeks
• D. 12 weeks

Correct answer: A

Rationale: Fetal movements (quickening) are first noticed by multigravida pregnant women at 16 to 20 weeks of gestation and gradually increase in frequency and strength. This is when the mother typically begins to feel the baby's movements. Choices B, C, and D are incorrect because fetal movements are not felt as early as 6, 8, or 12 weeks of gestation. At 6 weeks, the embryo's movements are not yet strong enough to be felt by the mother. By 8 weeks, the movements are still too subtle to be perceived. At 12 weeks, although fetal movements start, they are usually not strong enough to be felt by the mother.

3. A pregnant client is scheduled to undergo a transabdominal ultrasound, and the nurse provides information to the client about the procedure. The nurse provides which information?

• A. The procedure typically takes 10 to 30 minutes.
• B. She may need to drink fluids before the test and may not void until the test has been completed.
• C. A probe coated with gel will be inserted into the vagina.
• D. She will be positioned on her back, with her head elevated and turned slightly to one side.

Correct answer: B

Rationale: The correct answer is that the client may need to drink fluids before the test and may not void until the test has been completed. For a transabdominal ultrasound, the woman is positioned on her back with her head elevated and turned slightly to one side to prevent supine hypotension. A wedge or rolled blanket is placed under one hip to help her maintain this position comfortably. If a full bladder is necessary, the woman is instructed to drink several glasses of clear fluid 1 hour before the test and told that she should not void until the test has been completed. Warm mineral oil or transmission gel is spread over her abdomen, and the sonographer slowly moves a transducer over the abdomen to obtain a picture. The procedure typically takes 10 to 30 minutes, making choice A incorrect. Choice C is incorrect because a probe is not inserted into the vagina for a transabdominal ultrasound. Choice D is incorrect because the woman is positioned on her back with her head elevated and turned slightly to one side, not specifically on her back.

4. The nurse is assessing the dental status of an 18-month-old child. How many teeth should the nurse expect to examine?

• A. 6
• B. 8
• C. 12
• D. 16

Correct answer: C

Rationale: An 18-month-old child should have approximately 12 teeth. Children typically start getting teeth around 6 months of age. By subtracting 6 from the number of months in the child's age, you can calculate the expected number of teeth. For an 18-month-old child, 18 - 6 = 12 teeth. Therefore, the correct answer is 12 teeth. Choices A, B, and D are incorrect because they do not align with the expected dental development in an 18-month-old child.

5. A nurse assisting with data collection of the peripheral vascular system performs the Allen test. The nurse understands that this test is used to determine the patency of which blood vessel(s)?

• A. Capillaries
• B. Pedal pulses
• C. Femoral arteries
• D. Radial and ulnar arteries

Correct answer: D

Rationale: The nurse performs the Allen test to determine the patency of the radial and ulnar arteries. During the test, the nurse applies pressure over the client's ulnar and radial arteries simultaneously. The client is then asked to open and close the hand repeatedly, causing the hand to blanch. Subsequently, the nurse releases pressure from the ulnar artery while compressing the radial artery and checks the color of the extremity distal to the pressure point. If pinkness fails to return within 6 seconds, it indicates that the ulnar artery is insufficient, suggesting that the radial artery should not be used for obtaining a blood specimen. Choice A (Capillaries) is incorrect as the Allen test assesses the patency of larger arteries, not capillaries. Choice B (Pedal pulses) is incorrect as the Allen test specifically evaluates the radial and ulnar arteries, not the pedal pulses in the foot. Choice C (Femoral arteries) is incorrect as the Allen test focuses on the radial and ulnar arteries in the hand, not the femoral arteries in the leg.
