1. Which of the following foods is a complete protein?
- A. corn
- B. eggs
- C. peanuts
- D. sunflower seeds
Correct answer: B
Rationale: Eggs are considered a complete protein because they contain all nine essential amino acids required by the human body. In contrast, corn, peanuts, and sunflower seeds are incomplete proteins as they lack one or more essential amino acids. Corn, although a staple food for many cultures, is deficient in the amino acids lysine and tryptophan. Peanuts are low in the amino acid methionine, and sunflower seeds are low in lysine. Therefore, eggs are the correct answer as a complete protein source.
2. The LPN is about to give 100 mg Lopressor (metoprolol) to a client. Before administering the drug, they take the patient's vitals, which are as follows: Pulse: 58 Blood Pressure: 90/62 Respirations: 18/minute What action should the LPN take?
- A. Give the client half the prescribed dose and report the findings to the RN on duty.
- B. Give the client double the dose and report the findings to the RN on duty.
- C. Administer the drug and report the findings to the RN on duty.
- D. Hold the drug and report the findings to the RN on duty.
Correct answer: D
Rationale: Lopressor is given to treat hypertension, and a pulse of 58 and a blood pressure of 90/62 are considered low. To prevent the client from bottoming out, the drug should be held, and the findings reported to the RN, who should consult with the attending physician. LPNs should never adjust client dosing, as that is outside of their scope of practice. It is crucial to follow facility guidelines, which often recommend holding blood pressure medication at 60 bpm and a systolic pressure of 90 or less. By holding the drug and notifying the RN, the LPN ensures the client's safety and allows for appropriate assessment and decision-making by the healthcare team. Giving half the dose or double the dose without proper authorization can lead to serious complications and is considered unsafe practice.
3. A nurse is preparing to assess the fetal heart rate (FHR) of a client who is 14 weeks pregnant. Which piece of equipment does the nurse use to assess the FHR?
- A. Stethoscope
- B. Doppler transducer
- C. Fetoscope
- D. Pulse oximetry on the client and a fetoscope
Correct answer: B
Rationale: To assess the fetal heart rate of a client who is 14 weeks pregnant, the nurse should use a Doppler transducer. Fetal heart sounds can be heard with a fetoscope by 20 weeks of gestation. The Doppler transducer amplifies fetal heart sounds so that they are audible by 10 to 12 weeks of gestation, making it the most appropriate choice for this scenario. Fetal heart sounds cannot be heard with a stethoscope. Pulse oximetry is not used to auscultate fetal heart sounds, so it is an incorrect choice in this context.
4. 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.
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.
