Nursing Elites

1. A client in the cardiac step-down unit requires suctioning for excess mucous secretions. The nurse should be most careful to monitor the client for which dysrhythmia during this procedure?

• A. Bradycardia
• B. Tachycardia
• C. Premature ventricular beats
• D. Heart block

Correct answer: A

Rationale: During suctioning, a vagal response can be triggered leading to bradycardia. It is crucial for the nurse to monitor for this potential dysrhythmia. Tachycardia (Choice B) is less likely during suctioning and is not the priority. Premature ventricular beats (Choice C) and heart block (Choice D) can occur but are less common compared to bradycardia in this situation.

2. The chemotherapeutic DNA alkylating agents such as nitrogen mustards are effective because they:

• A. cross-link DNA strands with covalent bonds between alkyl groups on the drug and guanine bases on DNA.
• B. have few, if any, side effects.
• C. are used to treat multiple types of cancer.
• D. are cell-cycle-specific agents.

Correct answer: A

Rationale: Alkylating agents, such as nitrogen mustards, are effective chemotherapeutic agents because they cross-link DNA strands with covalent bonds between alkyl groups on the drug and guanine bases on DNA. This cross-linking interferes with DNA replication and transcription, leading to cell death. Choice B is incorrect because alkylating agents have numerous side effects, including alopecia, nausea, vomiting, and myelosuppression. Choice C is incorrect because while nitrogen mustards are used to treat multiple types of cancer like chronic lymphocytic leukemia, non-Hodgkin's lymphoma, and breast and ovarian cancer, their effectiveness is primarily due to DNA cross-linkage. Choice D is incorrect because alkylating agents are non-cell-cycle-specific agents, meaning they can act on cells in any phase of the cell cycle, not just on cells that are actively dividing.

3. A teenage client is admitted to the hospital because of an acetaminophen (Tylenol) overdose. Overdoses of acetaminophen can precipitate life-threatening abnormalities in which of the following organs?

• A. lungs
• B. liver
• C. kidneys
• D. adrenal glands

Correct answer: B

Rationale: Acetaminophen is extensively metabolized in the liver. An acetaminophen overdose can lead to severe liver damage and even liver failure, which can be life-threatening. Choices A, C, and D are incorrect. Acetaminophen overdose does not typically cause life-threatening problems in the lungs, kidneys, or adrenal glands. While prolonged acetaminophen use may increase the risk of renal dysfunction, a single overdose primarily affects the liver.

4. Due to a high census, it has been necessary for a number of clients to be transferred to other units within the hospital. Which client should be transferred to the postpartum unit?

• A. A 66-year-old female with gastroenteritis
• B. A 40-year-old female with a hysterectomy
• C. A 27-year-old male with severe depression
• D. A 28-year-old male with ulcerative colitis

Correct answer: B

Rationale: The best client to transfer to the postpartum unit is the 40-year-old female with a hysterectomy. The nurses on the postpartum unit will be knowledgeable about postoperative care and can manage any complications related to the surgery. Choices A and D would be more appropriately cared for on a medical-surgical unit due to their conditions. Choice C should be transferred to a psychiatric unit for specialized care related to severe depression.

5. The new mother asks why her baby has lost weight since he was born. The best explanation of the weight loss is:

• A. The baby is dehydrated due to polyuria.
• B. The baby is hypoglycemic due to lack of glucose.
• C. The baby is allergic to the formula the mother is giving him.
• D. The baby can lose up to 10% of weight due to meconium stool, loss of extracellular fluid, and initiation of breastfeeding.

Correct answer: D

Rationale: After birth, newborns can lose weight due to meconium stool, loss of extracellular fluid, and the initiation of breastfeeding. This weight loss is a normal and expected physiological process, and infants can lose up to 10% of their birth weight during this period. There is no indication of dehydration (polyuria), hypoglycemia (lack of glucose), or allergy to the formula as reasons for weight loss in newborns. Therefore, answers A, B, and C are incorrect. Answer D provides the most accurate explanation for the observed weight loss in the newborn.
