Adult Health 1 Exam 1
1. A client complains of pain at the IV site. Upon assessment, the nurse notes the site is warm, red, and swollen. What is the most likely cause of these findings?
- A. Phlebitis
- B. Infiltration
- C. Allergic reaction
- D. Fluid overload
Correct answer: A
Rationale: The correct answer is A, Phlebitis. Phlebitis is the inflammation of a vein, often caused by irritation from an IV catheter, resulting in warmth, redness, and swelling at the site. Infiltration (choice B) refers to the leaking of IV fluids into the surrounding tissues, causing swelling and pallor, not redness and warmth like in the scenario described. An allergic reaction (choice C) would present with itching, hives, or anaphylaxis, rather than localized warmth, redness, and swelling. Fluid overload (choice D) typically manifests as generalized edema, shortness of breath, and weight gain, not localized symptoms at the IV site.
2. The nurse is monitoring a client's intravenous infusion and observes that the venipuncture site is cool to the touch, swollen, and the infusion rate is slower than the prescribed rate. What is the most likely cause of this finding?
- A. The solution's rate is too rapid
- B. The client has phlebitis
- C. The infusion site is infected
- D. The infusion is infiltrated
Correct answer: D
Rationale: The correct answer is D. An infiltrated IV occurs when fluid leaks into the surrounding tissue, causing coolness, swelling, and a slow infusion rate. Choice A is incorrect because a rapid solution rate does not typically cause these specific symptoms. Choice B, phlebitis, presents with redness, warmth, and tenderness along the vein, not coolness. Choice C, infection, usually manifests with redness, warmth, and possibly purulent drainage, not coolness and swelling.
3. A client with a diagnosis of pneumonia is experiencing difficulty expectorating thick secretions. What intervention should the nurse implement to assist the client?
- A. Administer antibiotics as prescribed.
- B. Encourage increased fluid intake.
- C. Perform chest physiotherapy.
- D. Provide humidified oxygen.
Correct answer: B
Rationale: Encouraging increased fluid intake is the appropriate intervention to assist the client with pneumonia who is having difficulty expectorating thick secretions. Adequate hydration helps to thin the secretions, making them easier to cough up. Administering antibiotics (Choice A) is important for treating the infection itself but does not directly address the thick secretions. Chest physiotherapy (Choice C) may be beneficial in some cases but is not the initial intervention for thick secretions. Providing humidified oxygen (Choice D) can help with oxygenation but does not directly address the problem of thick secretions.
4. The nurse is preparing to administer a subcutaneous injection of heparin. What is the correct angle of insertion?
- A. 15 degrees
- B. 30 degrees
- C. 45 degrees
- D. 90 degrees
Correct answer: C
Rationale: The correct angle of insertion for a subcutaneous injection, such as heparin, is 45 degrees. This angle is appropriate as it helps to ensure proper delivery of the medication into the subcutaneous tissue. Option A (15 degrees) is too shallow for a subcutaneous injection and may result in the medication being deposited into the muscle. Option B (30 degrees) is also too shallow for subcutaneous injections. Option D (90 degrees) is used for intramuscular injections, not subcutaneous injections.
5. What is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space?
- A. Filtration
- B. Diffusion
- C. Osmosis
- D. Active transport
Correct answer: C
Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.
