1. The nurse is preparing to administer a subcutaneous injection of enoxaparin (Lovenox). Which site is most appropriate for the LPN/LVN to use?
- A. Deltoid muscle
- B. Ventrogluteal site
- C. Abdomen
- D. Dorsogluteal site
Correct answer: C
Rationale: The abdomen is the most appropriate site for administering subcutaneous injections of enoxaparin (Lovenox). Enoxaparin is typically administered in the abdomen due to better absorption and reduced risk of injury to underlying structures. The deltoid muscle is not recommended for subcutaneous injections of enoxaparin due to the potential risk of injury to underlying structures. The ventrogluteal and dorsogluteal sites are more appropriate for intramuscular injections rather than subcutaneous injections.
2. A client with a terminal illness is being educated by a healthcare provider about her decision to decline resuscitation in her living will. The client asks about the scenario of having difficulty breathing upon arrival at the emergency department.
- A. “We will apply oxygen through a tube in your nose.”
- B. “We will perform resuscitation efforts regardless of your wishes.”
- C. “You will receive only palliative care.”
- D. “We will ensure your comfort measures are met as per your advance directives.”
Correct answer: A
Rationale: Choice A is correct because applying oxygen through a tube in the nose provides comfort and aligns with the client's wishes for palliative care without resuscitation. This intervention can help alleviate breathing difficulties and maintain comfort without initiating full resuscitation efforts, respecting the client's decision. Choice B is incorrect as it goes against the client's expressed wish to decline resuscitation in her living will. Choice C is not the most appropriate response as it does not directly address the client's immediate concern of difficulty breathing and lacks specificity. Choice D, although focusing on comfort measures, is less specific than the correct choice A in addressing the client's immediate need for assistance with breathing.
3. The healthcare professional is preparing to administer potassium chloride intravenously to a client with hypokalemia. Which action is most important?
- A. Monitor the client's respiratory rate
- B. Check the client's urine output
- C. Administer the potassium chloride as a rapid IV push
- D. Dilute the potassium chloride in an appropriate IV solution
Correct answer: D
Rationale: The correct answer is to dilute the potassium chloride in an appropriate IV solution. Potassium chloride should never be administered as a rapid IV push as it can lead to severe complications, including cardiac arrhythmias. Diluting the medication and administering it slowly helps reduce the risk of adverse effects. Monitoring the client's respiratory rate (Choice A) and checking urine output (Choice B) are important aspects of patient assessment but not the most crucial when administering potassium chloride. Administering potassium chloride as a rapid IV push (Choice C) is dangerous and can result in serious harm to the client.
4. A client with diabetes mellitus is admitted with a blood glucose level of 600 mg/dL. What is the priority nursing action for the LPN/LVN?
- A. Administer insulin as prescribed.
- B. Administer oral hypoglycemic agents.
- C. Monitor blood glucose levels frequently.
- D. Provide a high-calorie diet.
Correct answer: A
Rationale: The correct answer is to administer insulin as prescribed. When a client with diabetes mellitus presents with a critically high blood glucose level like 600 mg/dL, the priority action is to lower the blood glucose level promptly to prevent complications. Insulin is the appropriate medication to rapidly reduce high blood glucose levels. Administering oral hypoglycemic agents may not act quickly enough in this critical situation. While monitoring blood glucose levels frequently is important, immediate intervention to lower the high blood glucose level takes precedence. Providing a high-calorie diet is contraindicated in this scenario as it would further elevate the blood glucose level.
5. When admitting a 5-month-old who has vomited 9 times in the past 6 hours, what should the healthcare provider observe for signs of which overall imbalance?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Increased serum hemoglobin levels
- D. Decreased serum potassium levels
Correct answer: B
Rationale: When a 5-month-old infant vomits multiple times, there is a risk of developing metabolic alkalosis due to the loss of stomach acid. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. It is caused by the loss of hydrogen ions from the body, often through vomiting. Metabolic acidosis (choice A) is unlikely in this scenario because it is more commonly associated with conditions like renal failure or diabetic ketoacidosis. Choice C, increased serum hemoglobin levels, is not typically a direct consequence of vomiting. Choice D, decreased serum potassium levels, may occur with vomiting but is not the primary concern when a patient is vomiting excessively.
