Correct Answer: C

Rationale: Fluid-volume deficit causes tachycardia. With correction of the imbalance, the heart rate should return to the expected range. An increase in hematocrit (Choice A) would indicate hemoconcentration, not a successful fluid replacement. An increase in respiratory rate (Choice B) could indicate respiratory distress or hypoxia, not improvement in fluid volume status. A decrease in capillary refill time (Choice D) may indicate improved peripheral perfusion but is not a direct indicator of fluid replacement success.

Correct Answer: C

Rationale: An ethical dilemma involves a situation where there are conflicting values or principles that make it difficult to make a clear decision. In the given scenarios, option C best represents an ethical dilemma as the family has conflicting feelings about initiating enteral tube feedings for their terminally ill father. This situation presents a clash between different values and beliefs, making it challenging to reach a resolution. Options A, B, and D do not illustrate conflicting values or principles that characterize an ethical dilemma. Option A describes a nurse's impairment, which is a concern but not a direct ethical dilemma. Option B depicts a potential breach of client autonomy and restraint use, which is an ethical issue but not a true ethical dilemma. Option D involves a client's personal decision regarding a durable power of attorney form, which, although important, does not present conflicting values or principles that define an ethical dilemma.

Correct Answer: A

Rationale: The correct answer is A: 'I am relying on support from our family during this time.' When a client is at the end of life, relying on support from family can be an effective coping mechanism. It allows the partner to share the emotional burden, seek comfort, and prevent feelings of isolation. Choice B reflects a reluctance to express feelings, which can hinder coping mechanisms by internalizing stress. Choice C suggests handling everything alone, which can lead to burnout and emotional strain due to the overwhelming responsibilities. Choice D, preferring to stay alone with the partner, may limit access to external support that could provide additional emotional and practical assistance during this challenging time, making it a less effective coping strategy.

Correct Answer: A

Rationale: The correct answer is to use tracheostomy covers when going outdoors. This instruction is important as it helps protect the airway from dust and other particles, reducing the risk of infection or irritation. Choice B is incorrect because maintaining sterile technique is crucial during tracheostomy care to prevent infections, but it is not the most pertinent instruction in this scenario. Choice C is incorrect as removing the outer cannula is not a routine cleaning procedure and should only be done by healthcare professionals when necessary. Choice D is incorrect because cleaning around the stoma with normal saline is not recommended as it can cause irritation to the skin and stoma site.

Correct Answer: C

Rationale: The correct answer is C. Limiting intake of beef to 4 ounces per week is an effective dietary modification to manage high cholesterol. Choice A is incorrect because the frequency and duration of exercise alone may not be sufficient to lower cholesterol significantly. Choice B is incorrect as proteins, including lean sources like poultry and fish, can be a part of a healthy diet. Choice D is incorrect as low-density lipoproteins, known as bad cholesterol, should be decreased, not increased, for heart health.
