Nursing Elites

1. A patient asks the nurse why they must have a heparin injection. What is the nurse's best response?

• A. Heparin will dissolve clots that you have.
• B. Heparin will reduce the platelets that make your blood clot.
• C. Heparin will work better than warfarin.
• D. Heparin will prevent new clots from developing.

Correct answer: D

Rationale: The correct answer is D: 'Heparin will prevent new clots from developing.' Heparin is an anticoagulant medication that helps prevent the formation of new blood clots. It does not dissolve existing clots (choice A), reduce platelets (choice B), or necessarily work 'better' than warfarin (choice C) but rather functions differently. The primary action of heparin is to prevent the development of new clots, especially in conditions where clot formation is a concern.

2. An 85-year-old client is diagnosed with hypernatremia due to lack of fluid intake and dehydration. The nurse knows that symptoms of hypernatremia include:

• A. Lack of thirst
• B. Pale skin
• C. Hypertension
• D. Swollen tongue

Correct answer: D

Rationale: Hypernatremia among elderly clients can result from dehydration and insufficient fluid intake, leading to sodium levels above 145 mEq/L. Common symptoms of hypernatremia include mental status changes, a thick or swollen tongue, excessive thirst, and flushed skin. Choice A, 'Lack of thirst,' is incorrect as hypernatremia typically presents with excessive thirst. Choice B, 'Pale skin,' is not a typical symptom of hypernatremia. Choice C, 'Hypertension,' is not a direct symptom of hypernatremia and is more commonly associated with other conditions like hypertension itself.

3. A client is brought into the emergency room where the physician suspects that he has cardiac tamponade. Based on this diagnosis, the nurse would expect to see which of the following signs or symptoms in this client?

• A. Fever, fatigue, malaise
• B. Hypotension and distended neck veins
• C. Cough and hemoptysis
• D. Numbness and tingling in the extremities

Correct answer: B

Rationale: Cardiac tamponade occurs when fluid or blood accumulates in the pericardium, preventing the heart from contracting properly. This leads to decreased cardiac output and is considered a medical emergency. Classic signs of cardiac tamponade include hypotension (low blood pressure) and distended neck veins due to the increased pressure around the heart. These signs result from the compromised ability of the heart to pump effectively. Choices A, C, and D are not typically associated with cardiac tamponade. Fever, fatigue, and malaise are non-specific symptoms that can be seen in various conditions. Cough and hemoptysis are more commonly associated with respiratory conditions, while numbness and tingling in the extremities are neurological symptoms not typically seen in cardiac tamponade.

4. A couple asks the nurse about risks of several birth control methods. What is the most appropriate response by the nurse?

• A. Norplant is safe and can be easily removed.
• B. Oral contraceptives should not be used by smokers.
• C. Depo-Provera is convenient with few side effects.
• D. The IUD provides protection against pregnancy and infection.

Correct answer: B

Rationale: The correct answer is that oral contraceptives should not be used by smokers. The use of oral contraceptives in a woman who smokes increases the risk of cardiovascular problems, such as thromboembolic disorders. This is due to the combined effect of smoking and hormonal contraceptives. Choices A, C, and D are incorrect because they do not address the specific risk associated with smoking and oral contraceptives. Norplant's safety and ease of removal, Depo-Provera's convenience with few side effects, and the IUD's protection against pregnancy and infection are important points but not directly related to the increased risks for smokers using oral contraceptives.

5. The physician has decided to perform a thoracentesis based on Mr. R's assessment. Which of the following actions from the nurse is most appropriate?

• A. Instruct the client not to talk during the procedure
• B. Assist the client to sit upright or slightly lean forward
• C. Insert a 20-gauge needle just above the 4th intercostal space
• D. Connect the needle to suction to remove fluid that has collected in the pleural space

Correct answer: A

Rationale: The correct answer is to instruct the client not to talk during the procedure. This is important to prevent air from being drawn into the pleural space during the thoracentesis. Choice B is incorrect because the client should be sitting upright or slightly leaning forward during the procedure to facilitate access to the pleural space. Choice C is incorrect as the nurse should not perform the thoracentesis procedure, which involves inserting a needle into the pleural space - this is the physician's responsibility. Choice D is incorrect as connecting the needle to suction to remove fluid is not the appropriate procedure for a thoracentesis. Thoracentesis is typically done to remove fluid or air for diagnostic or therapeutic purposes, not to connect to suction to remove fluid that has collected in the pleural space.
