Addressing Specific Question Types in the NR 509 Exam (PDF - 88 Questions)

The 88 questions in the NR 509 final exam (PDF format) likely encompass several question types. Here's a breakdown of common question types and strategies for tackling them:

• Multiple Choice (Single Best Answer): These questions present a scenario and ask you to select the single best answer from a list of options. The key is to carefully read the scenario, identify the core issue, and systematically eliminate incorrect options.

  • Example: A 60-year-old male presents with chest pain radiating down his left arm. ECG shows ST-segment elevation. Which of the following is the MOST likely diagnosis?

    • a) Stable Angina
    • b) Unstable Angina
    • c) Myocardial Infarction
    • d) Pericarditis

  • Strategy: Rule out angina as the ST elevation indicates myocardial damage. Pericarditis typically presents differently. MI is the most likely diagnosis.

• Multiple Response (Select All That Apply): These questions require you to identify all the correct answers from a list of options. These can be tricky, as you need to carefully evaluate each option and determine whether it applies to the scenario.

  • Example: Which of the following are risk factors for developing type 2 diabetes? (Select all that apply)

    • a) Obesity
    • b) Family History
    • c) Sedentary Lifestyle
    • d) Autoimmune Disorder
    • e) Advanced Age

  • Strategy: Obesity, family history, sedentary lifestyle, and advanced age are all established risk factors for type 2 diabetes. Autoimmune disorders are more closely linked to type 1 diabetes.

• Scenario-Based Questions: These questions present a patient scenario and ask you to apply your knowledge of pathophysiology to make clinical decisions. These questions often require you to integrate information from multiple sources, such as the patient's history, physical examination findings, and diagnostic tests.

  • Example: A 45-year-old female presents with fatigue, weight gain, and cold intolerance. Physical exam reveals a goiter. TSH is elevated, and T4 is low. What is the MOST likely cause of her symptoms?

    • a) Hyperthyroidism
    • b) Hypothyroidism
    • c) Cushing's Syndrome
    • d) Addison's Disease

  • Strategy: The symptoms and lab results point towards hypothyroidism (specifically, primary hypothyroidism due to the elevated TSH and low T4).

• Order/Prioritization Questions: These questions require you to prioritize interventions or actions based on their urgency or importance.

  • Example: A patient presents to the emergency department with severe respiratory distress. Place the following interventions in order of priority:

    • a) Administer oxygen
    • b) Obtain arterial blood gases (ABGs)
    • c) Intubate the patient
    • d) Assess airway patency

  • Strategy: The correct order would be: d) Assess airway patency, a) Administer oxygen, c) Intubate the patient (if necessary), b) Obtain arterial blood gases (ABGs). Airway and breathing are always the top priorities.

Sample Questions and Detailed Explanations (Modeled After NR 509 Style)

To further illustrate the type of questions you might encounter and how to approach them, consider these examples:

Question 1:

A 70-year-old male with a history of smoking presents with a chronic cough, shortness of breath, and wheezing. Pulmonary function tests reveal a decreased FEV1/FVC ratio. Which of the following is the MOST likely diagnosis?

a) Asthma b) Pneumonia c) Chronic Bronchitis d) Pulmonary Embolism

Explanation:

• Asthma is characterized by reversible airway obstruction, which is not typically seen in chronic smokers with a persistently decreased FEV1/FVC ratio.
• Pneumonia is an acute infection and would not present with chronic symptoms.
• Chronic Bronchitis, a type of COPD, is highly associated with smoking and causes chronic inflammation and obstruction of the airways, leading to a decreased FEV1/FVC ratio.
• Pulmonary Embolism can cause shortness of breath but is not typically associated with chronic cough and wheezing.

Correct Answer: c) Chronic Bronchitis

Question 2:

A patient with uncontrolled diabetes mellitus presents with polyuria, polydipsia, and glucosuria. Which of the following pathophysiological mechanisms BEST explains these symptoms?

a) Increased insulin sensitivity in peripheral tissues b) Decreased glucose reabsorption in the renal tubules c) Increased production of antidiuretic hormone (ADH) d) Decreased hepatic glucose production

Explanation:

• Increased insulin sensitivity would improve glucose uptake by cells, not lead to hyperglycemia.
• Decreased glucose reabsorption in the kidneys leads to glucosuria (glucose in the urine). The excess glucose in the urine acts as an osmotic diuretic, drawing water with it, leading to polyuria (frequent urination) and subsequent polydipsia (increased thirst).
• Increased ADH would lead to water retention, not polyuria.
• Decreased hepatic glucose production would help lower blood glucose levels.

Correct Answer: b) Decreased glucose reabsorption in the renal tubules

Question 3:

A patient is diagnosed with deep vein thrombosis (DVT) in the left leg. Which of the following Virchow's triad components is MOST likely contributing to this condition?

a) Increased blood pressure b) Arterial vasoconstriction c) Venous stasis d) Decreased platelet count

Explanation:

• Virchow's triad consists of: 1) endothelial injury, 2) hypercoagulability, and 3) venous stasis.
• Increased blood pressure and arterial vasoconstriction are not direct components of Virchow's triad.
• Decreased platelet count would actually decrease the risk of thrombosis.
• Venous stasis (slow blood flow) is a key component of Virchow's triad, allowing clotting factors to accumulate and increasing the risk of clot formation.

Correct Answer: c) Venous stasis
