What should be the primary action for a client who has just vomited 300 cc of bright red blood?

Correct Answer: D

Rationale: The correct first action for a client who has just vomited 300 cc of bright red blood is to check the blood pressure. This assessment is crucial to evaluate for hypotension, which could indicate significant blood loss and the need for immediate intervention. Documenting the vomiting is important for the client's medical record but not the initial priority. Increasing IV fluids and getting a complete blood count are necessary steps but should follow the assessment of the client's hemodynamic status.

Correct Answer: A

Rationale: The correct statement is, '"I should wear earplugs during the test,"?' as MRI scanners produce loud noises requiring ear protection. Metal objects, including jewelry, are not allowed inside the MRI room due to safety concerns related to the magnetic field. Choices B, C, and D are incorrect. Choice B is wrong because metal objects, including jewelry, are not permitted in the MRI room. Choices C and D are incorrect as having a pacemaker or an artificial hip raises concerns due to the magnetic field in MRI, requiring special precautions or considerations. It is crucial for individuals with such implants to inform their healthcare provider to assess the risks and determine the appropriate course of action.

Correct Answer: C

Rationale: Rifampin has the unusual effect of turning body fluids an orange color. Soft contact lenses might become permanently stained. Clients should be taught about these side effects to avoid unnecessary concern. Option A is incorrect as Rifampin does not cause the urine to turn blue. Option B is incorrect as the client is not infectious to others due to taking Rifampin for prophylaxis. Option D is incorrect as Rifampin does not cause the skin to take on a crimson glow.

Correct Answer: D

Rationale: The correct answer is Morton's neuroma. Morton's neuroma is a small mass or tumor in a digital nerve of the foot, causing symptoms such as pain and difficulty walking. Hallux valgus is commonly known as a bunion and involves the deviation of the big toe towards the other toes. Hammertoe is a condition where one or more toes are bent in a claw-like position. Plantar fasciitis is characterized by pain and inflammation in the arch of the foot, not typically associated with a mass causing difficulty walking.

Correct Answer: B

Rationale: In the scenario of a needle puncture requiring HIV prophylaxis, the CDC recommends initiating treatment with two non-nucleoside reverse transcriptase inhibitors, unless there is drug resistance. This regimen is preferred over other options such as a single protease inhibitor or two protease inhibitors due to its effectiveness and safety profile in this specific context. Non-nucleoside reverse transcriptase inhibitors are commonly used in post-exposure prophylaxis due to their activity against HIV and lower risk of resistance development compared to other antiretroviral drug classes.

Correct Answer: C

Rationale: The correct answer is, "What can I do to assist you to care for him at home?"? This response shows cultural sensitivity and respect for the family's values. In many Asian cultures, there is a strong tradition of caring for elders at home rather than in a long-term care facility. By offering assistance to the family in caring for their elderly member at home, the nurse shows understanding and support. Choices A, B, and D are incorrect because they do not acknowledge or respect the family's cultural beliefs and values regarding caring for elderly family members.

Correct Answer: C

Rationale: In an obstetrical emergency, the immediate action the nurse should take after the baby delivers is to suction the baby's mouth and nose to ensure the infant can breathe properly. This helps clear any potential obstructions and establish a clear airway. Cutting the umbilical cord (Choice B) and wrapping the baby in a clean blanket (Choice D) are important steps but should come after ensuring the baby's airway is clear. Placing extra padding under the mother (Choice A) is not a priority in this emergency situation as the focus should be on the baby's immediate needs for breathing and airway clearance.

Correct Answer: C

Rationale: The correct hand position for performing chest vibration is to flatten the hands. By flattening the hands over the area of the body where chest percussion is applied, vibrations can be conducted effectively to the chest to help loosen secretions. Cupping the hands may dampen vibrations, using the side of the hands reduces the surface area in contact with the chest, and spreading the fingers can lead to uneven pressure distribution. Therefore, flattening the hands provides the necessary contact and surface area to perform chest vibration efficiently.

Correct Answer: B

Rationale: In the scenario described, where multiple passengers on an airliner experience sudden weakness and breathing difficulty simultaneously, the most likely cause is chemical exposure. This is because a sudden onset of similar symptoms in a group of individuals suggests a common environmental factor affecting them. Options A, C, and D are less likely as they do not explain a sudden onset of symptoms in multiple individuals simultaneously. Asian flu (Option A) is a viral infection and would not typically result in sudden symptoms in multiple individuals at the same time. Bacterial pneumonia (Option C) is a localized infection and not a probable cause for a sudden onset of symptoms in a group. An allergic reaction (Option D) would usually occur in individuals with specific allergies rather than affecting a group of passengers at the same time.
