Nursing Elites

1. What are the expected changes on an ECG for a patient with hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. ST elevation
• D. Wide QRS complexes

Correct answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. Hypokalemia primarily manifests as flattened T waves on an ECG. While prominent U waves can be seen in hypokalemia, they are not as specific as flattened T waves. ST elevation is more commonly associated with conditions like myocardial infarction rather than hypokalemia. Wide QRS complexes are typically not a feature of hypokalemia on an ECG.

2. What should the healthcare provider do first when a patient is admitted with chest pain and possible acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Get IV access
• C. Auscultate heart sounds
• D. Obtain cardiac enzymes

Correct answer: A

Rationale: Administering sublingual nitroglycerin is the priority intervention when a patient presents with chest pain and suspected acute coronary syndrome. Nitroglycerin helps dilate blood vessels, improve blood flow to the heart, and relieve chest pain. It is crucial to address the pain and potential ischemia promptly to prevent further cardiac tissue damage. Getting IV access, auscultating heart sounds, and obtaining cardiac enzymes are important assessments and interventions, but administering nitroglycerin takes precedence in managing acute coronary syndrome.

3. A client is being taught about fecal occult blood testing (FOBT) for colorectal cancer screening. Which of the following statements should the nurse include in the teaching?

• A. Your provider will use a stool sample obtained during a digital rectal examination to perform the test.
• B. Your provider will recommend a stimulant laxative before the test to empty the bowel.
• C. You should start annual fecal occult blood testing for colorectal cancer screening at the age of 40.
• D. You should avoid corticosteroids before the test.

Correct answer: D

Rationale: The correct answer is D because the nurse should advise the client to avoid corticosteroids, anti-inflammatory medications, and vitamin C before fecal occult blood testing to prevent false-positive results. Choice A is incorrect as stool samples for FOBT are usually collected using a kit at home. Choice B is incorrect because stimulant laxatives are not typically used before FOBT. Choice C is incorrect as guidelines recommend starting colorectal cancer screening at the age of 50, not 40.

4. A nurse is administering insulin to a patient after misreading their glucose as 210 mg/dL instead of 120 mg/dL. What should the nurse monitor for?

• A. Monitor for hypoglycemia
• B. Monitor for hyperkalemia
• C. Administer glucose IV
• D. Document the incident

Correct answer: A

Rationale: The correct answer is to monitor for hypoglycemia. Insulin administration based on a misread glucose level can lead to hypoglycemia due to the unnecessary lowering of blood sugar levels. Monitoring for hypoglycemia involves assessing the patient's blood glucose levels frequently, observing for signs and symptoms such as shakiness, confusion, sweating, and administering glucose if hypoglycemia occurs. Choice B, monitoring for hyperkalemia, is incorrect as insulin administration typically lowers potassium levels. Choice C, administering glucose IV, is not the immediate action needed as the patient could potentially develop hypoglycemia from the excess insulin. Choice D, documenting the incident, is important but not the immediate priority when dealing with a potential hypoglycemic event.

5. A patient who experienced an acute episode of gastritis should avoid which type of foods?

• A. Avoid foods high in potassium
• B. Avoid foods high in sodium
• C. Increase exercise to reduce stress
• D. Drink milk as a snack

Correct answer: A

Rationale: The correct answer is A: Avoid foods high in potassium. Potassium-rich foods can exacerbate gastritis symptoms by irritating the stomach lining. Sodium (choice B) is not directly related to gastritis symptoms. Increasing exercise (choice C) can be beneficial for overall health but may not directly impact gastritis. Drinking milk (choice D) can provide temporary relief for some individuals with gastritis due to its coating effect, but it is not a universal recommendation as it can worsen symptoms in some cases.
