Nursing Elites

1. 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.

2. A client with type 1 diabetes mellitus is learning to administer insulin. What is the best site for the nurse to recommend for insulin injection?

• A. Abdomen
• B. Thigh
• C. Upper arm
• D. Buttock

Correct answer: A

Rationale: The correct answer is the abdomen. The abdomen is the recommended site for insulin injection due to its faster absorption rate compared to other sites. Insulin injected into the abdomen is absorbed more quickly, leading to better glycemic control. The thigh and upper arm are also common sites for insulin injection, but they have slower absorption rates than the abdomen. The buttock is not a preferred site for insulin injection due to inconsistent absorption and potential risk of injecting into muscle instead of fatty tissue.

3. Before a client undergoes a Magnetic Resonance Imaging (MRI) scan with contrast, what should the nurse assess?

• A. If the client has any metal implants
• B. If the client has allergies to iodine or shellfish
• C. If the client has a history of claustrophobia
• D. If the client has ever had a similar procedure before

Correct answer: A

Rationale: Before an MRI scan with contrast, the nurse should assess if the client has any metal implants. Metal implants can interfere with the magnetic field of the MRI, which can pose a risk to the client's safety and compromise the quality of the scan. Assessing for allergies to iodine or shellfish (Choice B) is important for contrast agents but not specific to metal implants. Claustrophobia assessment (Choice C) is relevant for MRI scans due to the confined space but not specific to metal implants. Past procedures (Choice D) are important for comparison but not directly related to the risks associated with metal implants during an MRI scan with contrast.

4. The client is 4 hours post-operative from a cesarean section and complains of gas pain and bloating. What non-pharmacological intervention can the nurse provide?

• A. Encourage the client to ambulate
• B. Apply a heating pad
• C. Provide a carbonated beverage
• D. Teach relaxation techniques

Correct answer: A

Rationale: The correct answer is to encourage the client to ambulate. Early ambulation helps alleviate gas pain and bloating by promoting gastrointestinal motility and reducing the accumulation of gas in the abdomen. Applying a heating pad may provide comfort for some types of pain but is not specifically effective for gas pain. Providing a carbonated beverage can actually worsen gas pain due to the introduction of more gas into the digestive system. Teaching relaxation techniques may be beneficial for overall comfort but may not directly address the gas pain and bloating experienced post-cesarean section.

5. A client with chronic obstructive pulmonary disease (COPD) is struggling to breathe. What should the nurse do first?

• A. Increase the oxygen flow rate according to the prescription
• B. Encourage the client to perform pursed-lip breathing
• C. Prepare for emergency intubation
• D. Assess the client's oxygen saturation and breath sounds

Correct answer: D

Rationale: The correct first action for a nurse when a client with COPD is struggling to breathe is to assess the client's oxygen saturation and breath sounds. This initial assessment is crucial in determining the severity of the client's condition and the appropriate intervention. Increasing the oxygen flow rate without proper assessment can potentially be harmful, as COPD clients have a risk of retaining carbon dioxide. Encouraging pursed-lip breathing can be beneficial but should come after assessing the client's current status. Emergency intubation is a drastic measure and should only be considered after a comprehensive assessment indicates the need for it.
