Nursing Elites

1. The nurse is teaching a client about the administration of a subcutaneous injection. Which site is most appropriate for this type of injection?

• A. Deltoid muscle
• B. Dorsogluteal muscle
• C. Ventrogluteal muscle
• D. Abdomen

Correct answer: D

Rationale: The abdomen is a common site for subcutaneous injections due to its accessibility and ample subcutaneous tissue. Subcutaneous injections are typically given in areas with a layer of fat between the skin and muscle, such as the abdomen, to allow for slow and consistent absorption of the medication. The deltoid muscle is more appropriate for intramuscular injections, not subcutaneous. The dorsogluteal muscle and ventrogluteal muscle are also more suited for intramuscular injections, not subcutaneous.

2. A client with asthma is prescribed an albuterol inhaler. Which instruction should the nurse provide?

• A. Use the inhaler only during an asthma attack
• B. Rinse your mouth after using the inhaler
• C. Shake the inhaler before each use
• D. Exhale fully before inhaling the medication

Correct answer: C

Rationale: The correct instruction for the nurse to provide is to shake the inhaler before each use. Shaking the inhaler ensures proper mixing of the medication before administration, which is crucial for its effectiveness. Choice A is incorrect because albuterol inhalers are often used as a preventive measure, not just during asthma attacks. Choice B is a good practice to prevent oral fungal infections associated with inhaled corticosteroids, not typically with albuterol. Choice D is important for proper inhaler technique, but the primary step before inhaling is shaking the inhaler to ensure the medication is well mixed.

3. 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.

4. A client with a diagnosis of chronic heart failure is prescribed digoxin. What is the most important assessment before administering this medication?

• A. Check blood pressure
• B. Assess heart rate
• C. Monitor respiratory rate
• D. Measure oxygen saturation

Correct answer: B

Rationale: The correct answer is to assess the heart rate before administering digoxin. Digoxin can lead to bradycardia, making it crucial to evaluate the heart rate to prevent potential complications. Checking blood pressure (Choice A) is important but not as critical as assessing the heart rate in this context. Monitoring respiratory rate (Choice C) and measuring oxygen saturation (Choice D) are not the most crucial assessments before administering digoxin, as the primary concern with this medication is its impact on heart rate.

5. 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.
