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. What is the term for the body's ability to defend itself against specific invading agents such as bacteria, toxins, viruses, and foreign bodies?

• A. Hormones
• B. Secretion
• C. Immunity
• D. Glands

Correct answer: C

Rationale: The correct answer is C: Immunity. Immunity refers to the body's ability to protect itself against specific invading agents like bacteria, toxins, viruses, and foreign bodies by recognizing and destroying them. It is a crucial defense mechanism that helps maintain health and prevent infections and diseases. Choices A, B, and D are incorrect because hormones are chemical messengers, secretion is the process of releasing substances, and glands are organs that produce and release substances, none of which specifically relate to the body's defense against invading agents.

3. Which of the following conditions in the client's history is a contraindication to the use of oral contraceptives?

• A. Hyperthyroidism.
• B. Thrombophlebitis.
• C. Diverticulosis.
• D. Hypocalcemia.

Correct answer: B

Rationale: Thrombophlebitis, which is inflammation of a vein with the formation of a clot, is a contraindication to the use of oral contraceptives due to an increased risk of thromboembolism. Clients with a history of thrombophlebitis or thromboembolic disorders should avoid oral contraceptives to prevent further complications like deep vein thrombosis or pulmonary embolism.

4. A client is being cared for by a nurse 2 hours after admission. The client has an SaO2 of 91%, exhibits audible wheezes, and is using accessory muscles when breathing. Which of the following classes of medication should the nurse expect to administer?

• A. Antibiotic
• B. Beta-blocker
• C. Antiviral
• D. Beta2 agonist

Correct answer: D

Rationale: The client's presentation with an SaO2 of 91%, audible wheezes, and use of accessory muscles indicates respiratory distress, likely due to bronchoconstriction. Beta2 agonists are the appropriate class of medications to administer in this situation as they act as bronchodilators, helping to relieve the bronchoconstriction and improve airflow to the lungs. Antibiotics, beta-blockers, and antivirals are not indicated for this client's respiratory distress symptoms.

5. A caregiver is caring for a 5-month-old infant who has manifestations of severe dehydration and a prescription for parenteral fluid therapy. The caregiver asks, 'What are the indications that my baby needs an IV?' Which of the following responses should the caregiver make?

• A. Your baby needs an IV because she is not producing any tears
• B. Your baby needs an IV because her fontanels are bulging
• C. Your baby needs an IV because she is breathing slower than normal
• D. Your baby needs an IV because her heart rate is decreasing

Correct answer: A

Rationale: The correct response is A: 'Your baby needs an IV because she is not producing any tears.' In infants, the inability to produce tears is a sign of severe dehydration. This is a crucial indication for the need for intravenous (IV) fluid therapy to rehydrate the infant. While the other options may also be symptoms of dehydration, the absence of tears is a more direct and specific indicator requiring immediate attention and intervention.
