LVN Safe and Effective Care Environment Test 3

Question 1

A patient diagnosed with diabetes mellitus is admitted for uncontrolled blood glucose levels. Which action by the nurse demonstrates understanding of safe medication administration?

Accepted Answer

Double-checking the patient's identification before administering insulin

Answer

Double-checking the patient's identification using at least two identifiers (e.g., name and date of birth) is a critical step in the 'five rights' of medication administration. This practice is essential for patient safety, preventing medication errors by ensuring the right patient receives the right medication. Administering insulin to the wrong patient could lead to severe, life-threatening complications.

Question 2

During a morning assessment, the nurse notes that a patient's intravenous (IV) site is swollen, cool to touch, and painful. What should the nurse do first?

Accepted Answer

Remove the IV catheter immediately

Answer

An IV site that is swollen, cool to touch, and painful are classic signs of infiltration, where IV fluid has leaked into the surrounding subcutaneous tissue. The immediate priority is to remove the IV catheter to prevent further tissue damage, discomfort, and potential complications. After removal, other interventions like applying a warm compress and documenting findings can follow.

Question 3

A patient with chronic obstructive pulmonary disease (COPD) has been prescribed oxygen therapy. What should the nurse prioritize when administering oxygen?

Accepted Answer

Adjusting the oxygen flow rate according to the patient's respiratory status

Answer

For patients with Chronic Obstructive Pulmonary Disease (COPD), oxygen administration requires careful monitoring and adjustment because excessive oxygen can suppress their hypoxic drive to breathe. The nurse must prioritize adjusting the oxygen flow rate according to the patient's respiratory status and oxygen saturation levels. This ensures adequate oxygenation without causing respiratory depression, which is crucial for safe and effective oxygen therapy in COPD patients.

Question 4

A nurse is preparing to administer medication to a patient with dysphagia. Which action demonstrates understanding of safe medication administration?

Accepted Answer

Administering each medication separately with a small amount of thickened liquid

Answer

For patients with dysphagia, administering each medication separately with a small amount of thickened liquid significantly reduces the risk of aspiration. Thickened liquids are easier for dysphagic patients to control and swallow safely, preventing them from entering the airway. Crushing all medications together or using a straw can be unsafe, and swallowing without water increases the risk of choking.

Question 5

When assessing a patient's skin integrity, which finding should the nurse prioritize reporting to the healthcare provider?

Accepted Answer

Ecchymosis (bruising) on the patient's forearm

Answer

Ecchymosis, or bruising, especially if new or unexplained, can indicate underlying issues such as trauma, bleeding disorders, or even abuse. While other findings like dry skin or a Stage 1 pressure ulcer are important, bruising can signify a more acute or systemic problem requiring prompt investigation. Prioritizing this finding ensures that potential serious causes are identified and addressed immediately.
