Contemporary Issues in Nursing

Correct Answer: A

Rationale: The correct answer is A: the federally coordinated National Disaster Medical System (NDMS). This system is specifically designed to provide medical care and support during disasters, including incidents involving mass casualties like the suicide bombing in the question. NDMS can rapidly deploy medical teams, equipment, and supplies to support local medical responses. Choice B is incorrect because local homeland communities may not have the necessary resources and capabilities to handle a large-scale medical emergency like this. Choice C is incorrect because while the Medical Reserve Corps can provide additional support, it may not have the same level of coordination and resources as the NDMS. Choice D is incorrect as the National Incident Management System focuses on overall coordination of all emergency response efforts, not specifically medical care.

Correct Answer: C

Rationale: Rationale for Correct Answer C: Irregular heartbeat is a significant symptom of hyperkalemia, which can be life-threatening. The nurse should evaluate capillary refill to assess perfusion. High potassium levels can affect cardiac function, leading to arrhythmias. Monitoring capillary refill provides insight into tissue perfusion, helping to assess the severity of the condition and guide appropriate interventions. Summary of Incorrect Choices: A: Drowsiness is not a typical symptom of hyperkalemia. Stimulating the patient every 30 minutes does not address the underlying issue. B: Confusion is not a common symptom of hyperkalemia. Asking the patient to state their name and birthdate does not address the cardiac implications of high potassium levels. D: Muscle cramps may occur with hyperkalemia but are not as critical as irregular heartbeat. Elevating the affected limb is not the priority in this situation.

Correct Answer: A

Rationale: The correct answer is A: address the letter to "To Whom It May Concern." This is the appropriate procedure when the applicant is unsure of the recipient's name and title. It is a professional and formal way to address a cover letter when the specific recipient is unknown. Option B is incorrect as addressing the letter to a generic title like "Nurse Recruiter" may not be appropriate if the recipient does not hold that specific title. Option C may be time-consuming and unnecessary if the applicant can use a more general salutation. Option D is incorrect because leaving the salutation blank can come across as unprofessional and lazy.

Correct Answer: D

Rationale: Step 1: The Law of Cure in homeopathy states that symptoms improve in the reverse order of their appearance. Step 2: The worsening of symptoms initially is known as a healing crisis or aggravation. Step 3: By remaining on the current regimen, the patient allows the body to go through the healing process. Step 4: This indicates that the body is responding to the remedy and working towards a deeper level of healing. Step 5: Discontinuing therapy or increasing potency/dosage may disrupt this natural healing process.

Correct Answer: A

Rationale: The correct answer is A: Vaccines and Level B Personal Protection Equipment (PPE). In the preparedness phase for a terrorist attack using anthrax, vaccines are crucial for prevention. Level B PPE provides respiratory protection and skin protection against anthrax spores. This is essential for healthcare workers and first responders. Choice B is incorrect as it mentions treatment for burns, which is not relevant to anthrax exposure. Decontamination and Level A PPE are not specifically needed for anthrax. Choice C is incorrect as it mentions radioactive fallout, which is not relevant to anthrax. Social distancing is also not effective in preventing anthrax exposure. Choice D is incorrect as it mentions incendiary devices and treatment for burns, which are not related to anthrax exposure. Identifying and detecting propellants is also not relevant to anthrax preparedness.
