1. What are the major electrolytes in the extracellular fluid?

• A. potassium and chloride
• B. potassium and phosphate
• C. sodium and chloride
• D. sodium and phosphate

Correct answer: C

Rationale: The correct answer is sodium and chloride. These two electrolytes are the major components of extracellular fluid. Potassium and phosphate (Choice B) are not the major electrolytes in the extracellular fluid. Potassium is primarily an intracellular ion, and phosphate is more abundant in the intracellular fluid and bones. Sodium and phosphate (Choice D) are also not the major electrolytes in the extracellular fluid. Chloride plays a crucial role in maintaining electrolyte balance and is predominantly found in extracellular fluid alongside sodium.

2. A client with a history of peptic ulcer disease arrives in the emergency department complaining of weakness and states that he vomited 'a lot of dark coffee-looking stomach contents.' The client is cool and moist to the touch. BP 90/50, HR 110, RR 20, T 98. Of the following physician orders, which will the nurse perform first?

• A. Initiate oxygen at 2 liters/nasal cannula.
• B. Start an IV of NS at 150 ml/hr
• C. Insert NG tube to low suction
• D. Attach the client to the ECG monitor

Correct answer: A

Rationale: The correct answer is to initiate oxygen at 2 liters/nasal cannula. The client is presenting signs of shock with hypotension, tachycardia, and cool, moist skin, which indicate poor tissue perfusion. Oxygen should be administered first to improve tissue oxygenation. While all interventions are important, oxygenation takes priority in the ABCs of emergency care. Starting an IV of NS, inserting an NG tube, and attaching the client to the ECG monitor are necessary interventions but should follow the priority of oxygen administration in this scenario.

3. A patient asks a nurse the following question: Exposure to TB can be best identified with which of the following procedures?

• A. Chest x-ray
• B. Mantoux test
• C. Breath sounds examination
• D. Sputum culture for Mycobacterium tuberculosis

Correct answer: B

Rationale: The Mantoux test, also known as the tuberculin skin test, is the most appropriate and accurate test to identify exposure to TB. This test involves injecting a small amount of PPD tuberculin under the top layer of the skin, and a positive reaction indicates exposure to the TB bacteria. Choice A, a chest x-ray, is useful for detecting active TB disease but not exposure. Choice C, a breath sounds examination, is not a specific test for TB exposure. Choice D, a sputum culture for Mycobacterium tuberculosis, is used to diagnose active TB infection rather than exposure.

4. The anemias most often associated with pregnancy are:

• A. folic acid and iron deficiency.
• B. folic acid deficiency and thalassemia.
• C. iron deficiency and thalassemia.
• D. thalassemia and B12 deficiency.

Correct answer: B

Rationale: Folic acid and iron deficiency anemia are the most common types of anemia associated with pregnancy. Approximately 50% of pregnant women experience this type of anemia. Iron deficiency anemia during pregnancy typically results from the increased plasma volume, rather than a decrease in iron levels. Moreover, if a woman has iron deficiency anemia before pregnancy, it often worsens during pregnancy. Folic acid deficiency is also prevalent during pregnancy due to the increased demand for this nutrient to support fetal development. Thalassemia and B12 deficiency, while types of anemia, are not as commonly associated with pregnancy compared to folic acid and iron deficiency anemia, making them incorrect choices in this context.

5. The death of a beloved spouse places the surviving partner in which type of crisis?

• A. maturational
• B. reactive
• C. nonreactive
• D. situational

Correct answer: D

Rationale: The correct answer is 'situational.' A situational crisis is an unexpected, unplanned event, such as the death of a spouse, which can lead to significant distress. Option A is incorrect because a maturational crisis is related to normal life transitions like getting married or retiring. Choices B and C are incorrect as they do not represent recognized crisis states in the context of the scenario provided.
