or a client with newly diagnosed cancer, the nurse formulates a nursing diagnosis of Anxiety related to the threat of death secondary to cancer diagnosis. Which expected outcome would be appropriate for this client?
- A. “Client verbalizes feelings of anxiety.”
- B. “Client doesn’t guess at prognosis.”
- C. “Client uses any effective method to reduce tension.”
- D. “Client stops seeking information.”
Correct Answer: A
Rationale: The correct answer is A because it reflects a measurable and client-centered outcome. Verbalizing feelings of anxiety indicates the client is acknowledging and addressing their emotions, which is essential in managing anxiety. Choice B is incorrect as it focuses on avoidance rather than expression of emotions. Choice C is incorrect as it doesn't specify the use of appropriate coping mechanisms. Choice D is incorrect as it suggests avoidance of seeking information, which may hinder the client's understanding and coping with the diagnosis.

The activation of B cells in humoral immunity is assisted by which of the following?
- A. Cytotoxic T cells
- B. Suppressor T cells
- C. Helper T cells
- D. Neutrophils
Correct Answer: C
Rationale: The correct answer is C: Helper T cells. Helper T cells play a crucial role in activating B cells by releasing cytokines that stimulate B cell proliferation and differentiation. They also help in the production of antibodies. Cytotoxic T cells (A) are involved in cell-mediated immunity, not humoral immunity. Suppressor T cells (B) regulate the immune response and do not directly assist in B cell activation. Neutrophils (D) are phagocytic cells involved in innate immunity, not in activating B cells in humoral immunity.
The nurse is preparing an intravenous infusion of phenytoin (Dilantin) as prescribed by the physician for the client with seizures. Which of the following solutions will the nurse plan to use to dilute this medication?
- A. Dextrose 5%
- B. Lactated Ringer’s solution
- C. Normal saline solution
- D. Dextrose 5% and half-normal saline (0.45%)
Correct Answer: C
Rationale: The correct answer is C: Normal saline solution. Phenytoin is incompatible with dextrose solutions, so options A and D are incorrect. Lactated Ringer's solution contains calcium, which can interact with phenytoin, leading to precipitation. Therefore, option B is also incorrect. Normal saline is the most compatible diluent for phenytoin, maintaining the drug's stability and effectiveness. It is essential to use the appropriate diluent to prevent adverse reactions or drug interactions.
The nurse is using critical thinking skills during the first phase of the nursing process. Which action indicates the nurse is in the first phase?
- A. Completes a comprehensive database
- B. Identifies pertinent nursing diagnoses
- C. Intervenes based on priorities of patient care
- D. Determines whether outcomes have been achieved
Correct Answer: A
Rationale: The correct answer is A because during the first phase of the nursing process (assessment), the nurse collects a comprehensive database of information about the patient's health status and needs. This data forms the foundation for identifying nursing diagnoses, planning interventions, and evaluating outcomes. Choices B, C, and D involve actions that occur in the subsequent phases of the nursing process (diagnosis, planning, and evaluation), not in the initial assessment phase. Therefore, A is the correct choice for the first phase.
Which type of neuron transmits impulses from the central nervous system to the muscles and glands?
- A. Afferent
- B. Affective
- C. Efferent
- D. Effective A1 PASSERS TRAINING, RESEARCH, REVIEW & DEVELOPMENT COMPANY MEDICAL SURGICAL NURSING SET M
Correct Answer: C
Rationale: The correct answer is C: Efferent neurons transmit impulses from the central nervous system to muscles and glands. This is because efferent neurons are responsible for carrying motor signals away from the central nervous system to control muscle movement and gland secretion.
Afferent neurons (choice A) transmit sensory information from the body to the central nervous system. Affective (choice B) is not a term used in neuroscience for describing neuron functions. Effective (choice D) is not a term used in neuroscience and does not describe the specific function of transmitting impulses from the central nervous system to muscles and glands.
Which of the following assessment findings would suggest to the home health nurse that the patient is developing congestive heart failure?
- A. orthopnea
- B. fever
- C. weight loss
- D. calf pain A1 PASSERS TRAINING, RESEARCH, REVIEW & DEVELOPMENT COMPANY MEDICAL SURGICAL NURSING SET O
Correct Answer: A
Rationale: Step 1: Orthopnea is a classic symptom of congestive heart failure (CHF) due to fluid accumulation in the lungs when lying flat.
Step 2: This symptom occurs because when lying down, the fluid redistributes, making it harder to breathe.
Step 3: Fever (choice B) is not typically associated with CHF unless there is an underlying infection.
Step 4: Weight loss (choice C) is more indicative of conditions like cancer or malnutrition, not CHF.
Step 5: Calf pain (choice D) is more commonly associated with deep vein thrombosis, not CHF.
Summary: Orthopnea is the best assessment finding indicating CHF, while the other choices are more likely related to different health conditions.
