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

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.

2. A client is complaining of difficulty walking secondary to a mass in the foot. The nurse should document this finding as:

Correct answer: D

Rationale: The correct answer is Morton's neuroma. Morton's neuroma is a small mass or tumor in a digital nerve of the foot, causing symptoms such as pain and difficulty walking. Hallux valgus is commonly known as a bunion and involves the deviation of the big toe towards the other toes. Hammertoe is a condition where one or more toes are bent in a claw-like position. Plantar fasciitis is characterized by pain and inflammation in the arch of the foot, not typically associated with a mass causing difficulty walking.

3. A small amount of bubbling is seen in the water seal of a pleural drainage system when a client coughs. What should the nurse do?

Correct answer: A

Rationale: A small amount of bubbling is a normal finding in the water seal of a pleural drainage system when a client coughs. It is only a problem to find continuous, excessive bubbling in the water seal, which indicates a leak. Checking the system for leaks would be appropriate if there is continuous, excessive bubbling. Clamping the chest tube or changing the drainage system is not necessary in response to a small amount of bubbling during a cough, as this is considered a normal finding.

4. A nurse is preparing to administer medications to a client via a nasogastric (NG) tube. Before administering the medication, the nurse must first take which action?

Correct answer: C

Rationale: Before administering medications through an NG tube, the nurse must first check the placement of the tube to prevent aspiration. This is done by aspirating gastric contents and measuring the pH. Checking the client's apical pulse is unrelated to NG tube medication administration. Checking when the last feeding was given is important but not a priority before administering medications. Checking when the last medications were given is also not directly related to ensuring the safe administration of medications through an NG tube. Ensuring the correct placement of the tube is crucial to prevent complications such as pulmonary aspiration.

5. A nurse manager asks a nurse to work overtime because of a short-staffing problem. The nurse has made plans to do Christmas shopping after work and does not want to work overtime. What is the most assertive response by the nurse to her nurse manager?

Correct answer: B

Rationale: The most assertive response in dealing with this conflict is the one that is direct and conveys a clear message in a positive manner. The nurse should assertively communicate her unavailability for overtime without being confrontational. Option A, "I'm not working overtime today," is too blunt and may come across as rude. Option C, "You know how I hate to work overtime," is not assertive but rather passive-aggressive. Option D, "I will if you need me, but I am not happy about this," is a passive-aggressive response as it implies compliance while expressing discontent. Option B, "I have plans after work and will not be able to work overtime," is the most appropriate response as it clearly states the nurse's unavailability without unnecessary aggression.
