1. What dietary alterations should a pregnant client with congenital heart disease expect?

• A. reduced calories and reduced fat
• B. caffeine and sodium restrictions
• C. decreased protein and increased complex carbohydrates
• D. fluid restriction and reduced calories

Correct answer: B

Rationale: In a pregnant client with congenital heart disease, caffeine should be restricted as it can increase heart rate, which is already under stress due to pregnancy. Sodium restrictions may be necessary to prevent fluid retention, which can worsen the client's heart condition. Decreasing calories, fat, protein, or fluid may not be appropriate as these can lead to nutrient deficiencies or inadequate energy intake, which is crucial during pregnancy. Therefore, options A, C, and D are not the expected dietary alterations in the client's diet during pregnancy with congenital heart disease.

2. Which of the following isoenzymes is elevated in a client who has had a myocardial infarction?

• A. CPK-BB
• B. CPK-MM
• C. CPK-MB
• D. CPK-MI

Correct answer: C

Rationale: CPK-MB is the correct answer as it is elevated in clients who have had a myocardial infarction. CPK-BB is elevated in clients with brain damage, and CPK-MM is elevated in clients with skeletal muscle damage. CPK-MI, mentioned in the rationale, does not exist, making it an incorrect choice.

3. What should be the primary action for a client who has just vomited 300 cc of bright red blood?

• A. Document the vomiting.
• B. Increase IV fluids.
• C. Get a complete blood count.
• D. Check the blood pressure.

Correct answer: D

Rationale: The correct first action for a client who has just vomited 300 cc of bright red blood is to check the blood pressure. This assessment is crucial to evaluate for hypotension, which could indicate significant blood loss and the need for immediate intervention. Documenting the vomiting is important for the client's medical record but not the initial priority. Increasing IV fluids and getting a complete blood count are necessary steps but should follow the assessment of the client's hemodynamic status.

4. What is the term for the tendency of a drug to combine with its receptor?

• A. potency
• B. efficacy
• C. kinetics
• D. affinity

Correct answer: D

Rationale: The correct answer is 'affinity.' Affinity refers to the close relationship or mutual attraction between a drug and its receptor, indicating the strength of the drug-receptor bonding. Potency (Choice A) is related to the dose of a drug needed to produce a specific effect. Efficacy (Choice B) refers to a drug's ability to generate the desired effect. Kinetics (Choice C) deals with forces affecting the motion of material bodies or changes in a system, which is not directly associated with the bonding between a drug and its receptor.

5. A nurse monitoring a client with a chest tube notes that there is no tidaling of fluid in the water seal chamber. After further assessment, the nurse suspects that the client's lung has reexpanded and notifies the healthcare provider. The healthcare provider verifies with the use of a chest x-ray that the lung has reexpanded, then calls the nurse to ask that the chest tube be removed. Which action should the nurse take first?

• A. Explain the procedure to the client, then remove the chest tube.
• B. Call the nursing supervisor.
• C. Inform the healthcare provider that removal of a chest tube is not a nursing procedure.
• D. Obtain petrolatum-impregnated gauze and ask another nurse to assist in removing the chest tube.

Correct answer: C

Rationale: The correct action for the nurse to take first is to inform the healthcare provider that removal of a chest tube is not a nursing procedure. Actual removal of a chest tube is the duty of a healthcare provider. If the healthcare provider insists that the nurse remove the tube, the nurse must contact the nursing supervisor. Some agencies' policies and procedures may permit an advanced practice nurse to remove a chest tube, but there is no information in the question to indicate that the nurse is an advanced practice nurse. Choice A is incorrect because the nurse should not proceed with removing the chest tube without proper authorization. Choice B is incorrect as calling the nursing supervisor should come after clarifying with the healthcare provider. Choice D is incorrect as the nurse should not begin the process of removing the chest tube without proper guidance and authorization.
