1. When caring for a client on pressure support ventilation (PSV), which statement by the nurse indicates an understanding of PSV?
- A. It keeps the alveoli open and prevents atelectasis.
- B. It allows preset pressure delivered during spontaneous ventilation.
- C. It guarantees minimal minute ventilator.
- D. It delivers a preset ventilatory rate and tidal volume to the client.
Correct answer: B
Rationale: Pressure support ventilation (PSV) is a mode that delivers a preset pressure when the client initiates a breath. This support helps the client to breathe spontaneously by reducing the work of breathing. The correct statement indicating an understanding of PSV is that it allows preset pressure to be delivered during spontaneous ventilation, as it assists the client's efforts without controlling the rate or volume of each breath.
2. Which chamber of the heart receives oxygenated blood from the lungs?
- A. Left atrium
- B. Right atrium
- C. Left ventricle
- D. Right ventricle
Correct answer: A
Rationale: The correct answer is A, the left atrium. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. This blood is then pumped into the left ventricle before being circulated throughout the body. The right atrium, represented by choice B, actually receives deoxygenated blood from the body through the vena cava. Choices C and D, the left ventricle and right ventricle respectively, are chambers involved in pumping blood out of the heart to the body and lungs, rather than receiving blood from the lungs.
3. The correct method for determining the vastus lateralis site for I.M. injection is to:
- A. Locate the upper aspect of the upper outer quadrant of the buttock about 5 to 8 cm below the iliac crest
- B. Palpate the lower edge of the acromion process and the midpoint lateral aspect of the arm
- C. Palpate a 1†circular area anterior to the umbilicus
- D. Divide the area between the greater femoral trochanter and the lateral femoral condyle into thirds, and select the middle third on the anterior of the thigh
Correct answer: D
Rationale: The vastus lateralis site is located in the middle third of the thigh.
4. A healthcare professional is preparing to measure an infant's temperature. Which of the following actions should the healthcare professional take?
- A. Place the tip of the thermometer under the center of the infant's axilla
- B. Pull the pinna of the infant's ear forward before inserting the probe
- C. Insert the probe 3.8 cm (1.5in) into the infant's rectum
- D. Insert the thermometer in front of the infant's tongue
Correct answer: A
Rationale: When measuring an infant's temperature, the most appropriate and non-invasive method is to place the tip of the thermometer under the center of the infant's axilla (armpit). This method is safe, quick, and comfortable for the infant. Inserting the probe into the rectum is invasive and not recommended for routine temperature measurement in infants. Inserting the thermometer in front of the infant's tongue is not a reliable method for measuring temperature. Pulling the pinna of the ear forward is a technique used for adults, not infants.
5. Which of the following is included in Orem’s theory?
- A. Maintenance of a sufficient intake of air
- B. Self-perception
- C. Love and belonging
- D. Physiological needs
Correct answer: A
Rationale: Orem's theory, also known as the Self-Care Deficit Nursing Theory, focuses on individuals' ability to perform self-care to maintain health and well-being. One specific component of this theory is the maintenance of a sufficient intake of air, which is crucial for sustaining life and overall health. Option A is the correct choice as it directly relates to meeting physiological needs, such as the intake of air, to support optimal functioning and health. Choices B, C, and D are incorrect as they do not specifically align with Orem's emphasis on self-care and meeting physiological requirements.
