1. The nurse is teaching a group of new mothers about infant care. Which topic should the nurse prioritize?
- A. signs of infant dehydration
- B. proper diaper changing techniques
- C. immunization schedule
- D. breastfeeding positions
Correct answer: A
Rationale: The correct answer is A: signs of infant dehydration. Recognizing signs of dehydration is crucial for ensuring the health and well-being of infants. Dehydration can be life-threatening for infants if not addressed promptly. While proper diaper changing techniques, immunization schedules, and breastfeeding positions are also important topics in infant care, being able to identify signs of dehydration takes precedence as it requires immediate attention to prevent serious consequences.
2. A 16-year-old male client who has been treated in the past for a seizure disorder is admitted to the hospital. Immediately after admission, he begins to have a grand mal seizure. Which action should the nurse take?
- A. Obtain assistance in holding him to prevent injury.
- B. Observe him carefully.
- C. Call a CODE.
- D. Place a padded tongue blade between the teeth.
Correct answer: B
Rationale: During a grand mal seizure, the priority action for the nurse is to ensure the safety of the client. Observing the client carefully allows the nurse to monitor the seizure activity, the client's breathing, and any signs of distress without interfering with the seizure process. Restraining the client or placing objects in the mouth can lead to injury and should be avoided. Calling a CODE is not appropriate for a seizure as it is a normal response to the client's condition.
3. A client with depression remains in bed most of the day, declines activities, and refuses meals. Which nursing problem has the greatest priority for this client?
- A. Loss of interest in diversional activities.
- B. Social isolation.
- C. Refusal to address nutritional needs.
- D. Low self-esteem.
Correct answer: C
Rationale: The correct answer is C: 'Refusal to address nutritional needs.' In this scenario, the client's refusal to eat and address their nutritional needs poses an immediate threat to their physical health. Without proper nutrition, the client is at risk of malnutrition and its associated complications. While addressing social isolation, low self-esteem, and loss of interest in diversional activities are important aspects of holistic care for a client with depression, ensuring proper nutrition takes precedence due to the critical impact it has on the client's physical well-being. Therefore, the priority is to address the client's refusal to eat and address their nutritional needs to prevent further deterioration of their health.
4. A client with an eating disorder tells the RN, 'I’ve been eating only 400 calories per day and have been taking diuretics to lose weight.' What is the RN’s best response?
- A. “Your diet is very harmful and needs to be changed immediately.”
- B. “It’s important to monitor your calorie intake carefully.”
- C. “Have you noticed any physical effects from this low-calorie diet?”
- D. “The diuretics could be causing your body to lose essential nutrients.”
Correct answer: D
Rationale: The correct response is D. By addressing the potential harm of diuretics and the low-calorie diet, the nurse effectively addresses both aspects of the client's disordered eating behavior. Choice A is too direct and does not provide information on the specific issue of diuretics. Choice B focuses solely on monitoring calorie intake without addressing the use of diuretics. Choice C inquires about physical effects but does not address the overall risks associated with diuretics and low-calorie intake.
5. The nurse is teaching a nursing student about the minimal effective concentration (MEC) of antibiotics. Which statement by the nursing student indicates understanding of this concept?
- A. A serum drug level greater than the MEC ensures that the drug is bacteriostatic.
- B. A serum drug level greater than the MEC broadens the spectrum of the drug.
- C. A serum drug level greater than the MEC helps eradicate bacterial infections.
- D. A serum drug level greater than the MEC increases the therapeutic index.
Correct answer: C
Rationale: The MEC is the minimum amount of drug needed to halt the growth of a microorganism. A level greater than the MEC helps eradicate infections. Drugs at or above the MEC are usually bactericidal, not bacteriostatic. Therefore, choice A is incorrect. Broadening the spectrum of a drug refers to its range of activity against different microorganisms, which is not directly related to MEC. Thus, choice B is incorrect. Increasing the therapeutic index involves maximizing the effectiveness of a drug while minimizing its toxicity, which is not specifically related to MEC. Therefore, choice D is also incorrect.
