When medications have an additive, synergistic, or antagonistic effect on a tissue, a ________ reaction has occurred.
- A. pharmaceutical
- B. pharmacodynamic
- C. pharmacokinetic
- D. drug incompatibility
Correct Answer: B
Rationale: The correct answer is 'pharmacodynamic.' Pharmacodynamics pertain to the effect of a drug on receptors, explaining how drugs affect tissues. Pharmaceutical reactions refer to chemical reactions between drugs before administration or absorption, not their effect on tissues. Pharmacokinetic reactions involve how the body affects the drug, not the tissue. Drug incompatibilities are essentially pharmaceutical reactions, not the specific effects on tissues seen in pharmacodynamic reactions.

There are many types of torts that can be committed against clients. They include all of the following except:
- A. assault.
- B. battery.
- C. negligence.
- D. felony.
Correct Answer: D
Rationale: The correct answer is 'felony.' Felonies are serious crimes punishable by time in prison and are not considered types of torts. Types of torts include assault, battery, negligence, as well as other examples like slander, invasion of privacy, false imprisonment, and fraud. Assault involves the threat of harm, battery involves physical harm, and negligence involves a failure to exercise reasonable care. These are all civil wrongs (torts) rather than criminal offenses (felonies), making 'felony' the correct choice.
Some drugs are excreted into bile and delivered to the intestines. Prior to elimination from the body, the drug might be absorbed. This process is known as:
- A. hepatic clearance.
- B. total clearance.
- C. enterohepatic cycling.
- D. first-pass effect.
Correct Answer: C
Rationale: The correct answer is 'enterohepatic cycling.' This process involves drugs being excreted into bile, delivered to the intestines, reabsorbed into the circulation, and can prolong the drug's presence in the body. 'Hepatic clearance' (Choice A) refers to the amount of drug eliminated by the liver. 'Total clearance' (Choice B) is the sum of all types of clearance including renal, hepatic, and respiratory. 'First-pass effect' (Choice D) is the amount of drug absorbed from the GI tract and metabolized by the liver before entering circulation, reducing the amount of drug available for systemic circulation.
The nurse is caring for a dying client who has persistently requested that the nurse 'help her to die and be in peace.' According to the Code of Ethics for Nurses, the nurse should:
- A. Ask the client whether she has signed the advance directives document.
- B. Tell the client that he or she will ask another nurse to care for her.
- C. Instruct the client that only a physician can legally assist in suicide.
- D. Try to make the client as comfortable as possible, but refuse to assist in death.
Correct Answer: D
Rationale: The correct answer is to try to make the client as comfortable as possible but refuse to assist in death. According to the Code of Ethics for Nurses, nurses are committed to providing compassionate care, respecting the dignity and rights of the dying person. In this situation, it is important for the nurse to focus on providing comfort and support to the client while upholding ethical standards. Choice A is incorrect because discussing advance directives does not address the immediate request for assistance in dying. Choice B is incorrect as it does not address the ethical dilemma presented. Choice C is incorrect because instructing the client that only a physician can assist in suicide does not fully address the complexity of the situation or the nurse's role in providing end-of-life care.
Before administering Theodur to a 10-year-old being treated for asthma, the nurse should check the:
- A. Urinary output
- B. Blood pressure
- C. Pulse
- D. Temperature
Correct Answer: C
Rationale: The correct answer is to check the pulse. Theodur is a bronchodilator used in asthma treatment, and one of the side effects is tachycardia (increased heart rate). Therefore, it is essential to assess the pulse rate before administering Theodur to monitor for any potential tachycardia. Checking urinary output (Choice A), blood pressure (Choice B), and temperature (Choice D) are not directly related to the immediate side effects of bronchodilators like Theodur in this context, making them unnecessary assessments.
A twenty-one-year-old man suffered a concussion, and the MD ordered an MRI. The patient asks, 'Will they allow me to sit up during the MRI?' The correct response by the nurse should be:
- A. "I will have to talk to the doctor about letting you sit upright during the test."?
- B. "You will be positioned in the reverse Trendelenburg position to maximize the view of the brain."?
- C. "The radiologist will let you know."?
- D. "You will have to lie down on your back during the test."?
Correct Answer: D
Rationale: The correct answer is to inform the patient that they will have to lie down on their back during the MRI. This positioning is necessary for the scan to obtain accurate images of the brain. Choice A is incorrect because the decision on the positioning during the MRI is typically determined by the imaging protocol and not subject to negotiation during the test. Choice B is incorrect as the reverse Trendelenburg position is not commonly used during MRI scans. Choice C is incorrect because the radiologist does not usually make decisions on patient positioning during the MRI; it is predetermined by the imaging requirements.
