Adult Health 2 Exam 1
1. The nurse is caring for a client with an intravenous infusion of normal saline. The client reports pain and swelling at the IV site. What is the nurse’s priority action?
- A. Slow the rate of infusion
- B. Apply a warm compress to the site
- C. Discontinue the IV infusion
- D. Elevate the affected arm
Correct answer: C
Rationale: The correct answer is to discontinue the IV infusion (Choice C). Pain and swelling at the IV site can indicate infiltration or phlebitis, which are serious complications that require immediate action. Slowing the rate of infusion (Choice A) may not address the underlying issue and can potentially worsen the condition. Applying a warm compress (Choice B) may provide temporary relief but does not address the need to discontinue the infusion. Elevating the affected arm (Choice D) is not the priority in this situation; discontinuing the infusion takes precedence to prevent further harm.
2. The healthcare provider is preparing to administer an IM injection to an adult client. Which site is the preferred location for this injection?
- A. Deltoid muscle
- B. Vastus lateralis muscle
- C. Ventrogluteal muscle
- D. Dorsogluteal muscle
Correct answer: C
Rationale: The ventrogluteal site is the preferred site for IM injections in adults due to its muscle mass and low risk of nerve injury. The deltoid muscle, although commonly used for vaccines in adults due to easy accessibility, has a smaller muscle mass making it less ideal for IM injections. The vastus lateralis muscle is typically used in infants and young children, not in adults. The dorsogluteal site has a higher risk of injury to the sciatic nerve and is no longer recommended for IM injections in any age group.
3. When using a metered-dose inhaler (MDI), which step is most important for ensuring effective medication delivery?
- A. Exhale completely before using the inhaler
- B. Inhale quickly while pressing down on the inhaler
- C. Shake the inhaler for 10 seconds before use
- D. Hold breath for 5 seconds after inhaling
Correct answer: A
Rationale: The correct step to ensure effective medication delivery when using a metered-dose inhaler (MDI) is to exhale completely before using the inhaler. This action helps create more space in the lungs for the medication to reach deeply into the airways. Inhaling quickly while pressing down on the inhaler (Choice B) may cause the medication to impact the throat rather than reaching the lungs. Shaking the inhaler for 10 seconds before use (Choice C) is important to mix the medication but not the most crucial step for effective delivery. While holding the breath for 5 seconds after inhaling (Choice D) can help the medication stay in the lungs momentarily, exhaling completely before inhalation is more critical for optimal drug deposition.
4. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which laboratory finding is most indicative of this condition?
- A. Serum glucose of 180 mg/dL
- B. Blood pH of 7.30
- C. Positive urine ketones
- D. Serum bicarbonate of 25 mEq/L
Correct answer: C
Rationale: The correct answer is C: Positive urine ketones. In diabetic ketoacidosis (DKA), the body breaks down fat for energy due to a lack of insulin, leading to ketone production. Positive urine ketones are a hallmark laboratory finding in DKA as they directly reflect the presence of ketosis. Choice A, serum glucose of 180 mg/dL, may be elevated in DKA, but it is not specific to this condition. Choice B, blood pH of 7.30, often shows acidosis in DKA, but urine ketones are more specific to the presence of ketosis. Choice D, serum bicarbonate of 25 mEq/L, would typically be low in DKA due to acidosis rather than elevated.
5. The healthcare provider is preparing to administer an intramuscular injection to an adult client. Which site is the preferred location for this injection?
- A. Deltoid muscle.
- B. Vastus lateralis muscle.
- C. Ventrogluteal muscle.
- D. Dorsogluteal muscle.
Correct answer: C
Rationale: The ventrogluteal site is preferred for intramuscular injections in adults due to its muscle mass and lower risk of nerve injury. The deltoid muscle is more commonly used for vaccines in adults, the vastus lateralis muscle is preferred in infants and young children, and the dorsogluteal muscle is associated with a higher risk of nerve injury and is no longer recommended for intramuscular injections.
