Nursing Elites

1. The client with high blood pressure is being taught by the nurse to avoid adding salt during cooking. What effect does sodium have on blood pressure?

• A. It decreases the viscosity of blood
• B. It leads to increased fluid retention
• C. It causes vasoconstriction of the blood vessels
• D. It enhances the excretion of potassium

Correct answer: C

Rationale: The correct answer is C: 'It causes vasoconstriction of the blood vessels.' Sodium can lead to vasoconstriction, which narrows the blood vessels, increasing resistance to blood flow and subsequently raising blood pressure. Choices A, B, and D are incorrect. Sodium does not decrease blood viscosity, but it can lead to fluid retention, which increases blood volume and pressure. It does not enhance the excretion of potassium; instead, high sodium intake can lead to potassium excretion by the kidneys.

2. 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.

3. A client with a diagnosis of hypothyroidism is prescribed levothyroxine (Synthroid). What is the most important instruction the nurse should provide?

• A. Take the medication in the morning on an empty stomach
• B. Take the medication with food
• C. Report any symptoms of hyperthyroidism
• D. Do not discontinue the medication abruptly

Correct answer: C

Rationale: The correct answer is C: 'Report any symptoms of hyperthyroidism.' Symptoms of hyperthyroidism, such as palpitations or tremors, may indicate an excessive dose of levothyroxine and should be reported to the healthcare provider for proper adjustment of the medication. Choice A is incorrect because levothyroxine is usually taken in the morning on an empty stomach to maximize absorption. Choice B is incorrect because taking levothyroxine with food can interfere with its absorption. Choice D is incorrect because discontinuing levothyroxine abruptly can lead to a worsening of hypothyroidism symptoms.

4. Which structures are located in the subcutaneous layer of the skin?

• A. Sebaceous and sweat glands
• B. Melanin and keratin
• C. Sensory receptors and hair follicles
• D. Adipose cells and blood vessels

Correct answer: D

Rationale: The correct answer is D: Adipose cells and blood vessels. The subcutaneous layer, also known as the hypodermis, primarily consists of adipose (fat) tissue and blood vessels. Adipose tissue provides insulation, energy storage, and cushioning, while blood vessels supply nutrients and oxygen. Sebaceous and sweat glands are located in the dermis, which is the layer beneath the epidermis. Melanin and keratin are components of the epidermis, responsible for skin color and waterproofing, respectively. Sensory receptors and hair follicles are found in the dermis and extend into the subcutaneous layer but are not exclusive to it.

5. A client is being treated for heart failure. What should the nurse monitor to evaluate treatment effectiveness?

• A. Daily weight
• B. Electrolyte levels
• C. Urine output
• D. All of the above

Correct answer: D

Rationale: Monitoring daily weight, electrolyte levels, and urine output is crucial in evaluating treatment effectiveness for heart failure. Daily weight monitoring helps assess fluid retention or loss, changes in electrolyte levels can indicate imbalances affecting heart function, and urine output monitoring provides insights into kidney function and fluid balance. Therefore, all options are essential components in assessing the patient's fluid status and response to treatment, making 'All of the above' the correct answer. Choices A, B, and C are incorrect individually as they only represent partial aspects of monitoring heart failure treatment effectiveness.
