What is the appropriate ratio of chest compressions to rescue breaths for adult CPR?

Correct Answer: C

Rationale: The appropriate ratio of chest compressions to rescue breaths for adult CPR is 30 compressions to 2 breaths. This means that after every 30 chest compressions, two rescue breaths should be given. This ratio helps in maintaining oxygen circulation in the body while also ensuring that the heart is being effectively pumped to circulate blood. The emphasis on chest compressions is critical in maintaining blood flow to vital organs during cardiac arrest, while the rescue breaths help in providing oxygen to the patient's lungs. This ratio is recommended by organizations like the American Heart Association for performing high-quality adult CPR.

Correct Answer: B

Rationale: The presentation described is consistent with nummular eczema, also known as discoid eczema. Nummular eczema typically presents as circular or oval-shaped patches of eczematous rash with fine scaling and central clearing. It is often pruritic and can be triggered by exposure to irritants such as new soaps or laundry detergents. The distribution on the trunk and proximal extremities is also typical for nummular eczema. Tinea corporis (ringworm) would present with a more raised, scaly, and well-defined border with central clearing. Pityriasis rosea presents with a herald patch followed by smaller oval or round lesions in a "Christmas tree" distribution. Lichen planus would present with polygonal, purplish, flat-topped papules typically located on flexural surfaces and extremities.

Correct Answer: A

Rationale: The ethical principle that should guide the nurse's decision-making in this situation is beneficence, which emphasizes the nurse's obligation to act in the best interest of the patient. In this scenario, the nurse must balance the patient's request for pain medication with considerations related to the patient's history of substance abuse. The nurse should prioritize providing effective pain relief for the patient while also considering the potential risks of administering medication to someone with a history of substance abuse. By focusing on beneficence, the nurse can make decisions that promote the well-being and best interests of the patient, taking into account both the immediate need for pain relief and the patient's history of substance abuse.

Correct Answer: B

Rationale: Magnesium sulfate is used to prevent eclampsia, but it can lead to toxicity if levels become too high. One common sign of magnesium toxicity is increased deep tendon reflexes, also known as hyperreflexia. This occurs because magnesium is a muscle relaxant, and elevated levels can lead to over-relaxation of muscles, causing an exaggerated reflex response. Other signs of magnesium toxicity include respiratory depression, decreased urine output, and cardiac arrest. Therefore, in a woman receiving intravenous magnesium sulfate during labor, an increase in deep tendon reflexes would indicate potential toxicity and require immediate intervention.

Correct Answer: B

Rationale: Nurse Crissel likely informed the participants that HIV is not casually transmitted through activities like kissing. HIV transmission primarily occurs through activities that involve the exchange of bodily fluids, such as blood, semen, vaginal fluids, and breast milk. Accidental blood exposure, unprotected sex, and mother to child transmission are known routes of HIV transmission due to the direct exchange of bodily fluids containing the virus. However, the virus is not spread through saliva, including activities like kissing, which do not involve the exchange of significant amounts of bodily fluids.

Correct Answer: A

Rationale: The presentation described is characteristic of acute angle-closure glaucoma. This condition typically presents with sudden-onset severe eye pain, headache, nausea, and vomiting. On examination, the affected eye may appear red due to conjunctival injection, and there may be a steamy cornea due to corneal edema. The mid-dilated, non-reactive pupil is a key finding in angle-closure glaucoma, as the iris bombe (forward movement of the peripheral iris) blocks the drainage angle, leading to increased intraocular pressure. If left untreated, acute angle-closure glaucoma can result in irreversible vision loss. Immediate intervention is crucial to lower the intraocular pressure and prevent further damage to the optic nerve. Prompt referral to an ophthalmologist for definitive treatment is necessary in cases of suspected acute angle-closure glaucoma.

Correct Answer: A

Rationale: The most appropriate intervention for the palliative nurse to prioritize in this situation is to arrange for family members or loved ones to be present at the patient's bedside. Having loved ones nearby can provide emotional support, comfort, and reassurance to the patient during their final moments. This can help alleviate the fear and anxiety the patient is experiencing about dying alone. Additionally, it can contribute to a sense of connectedness and peace for both the patient and their loved ones during this challenging time. Offering practical solutions to address the patient's emotional needs is key in providing holistic palliative care.

Correct Answer: A

Rationale: Maternal dehydration can contribute to a prolonged latent phase during labor. Dehydration can lead to reduced blood volume and electrolyte imbalances, which can result in ineffective uterine contractions. Without adequate hydration, the uterus may not contract effectively, causing irregular and infrequent contractions. It is important for the nurse to assess the woman's hydration status and encourage her to stay hydrated during labor to help regulate contractions and progress labor.

Correct Answer: D

Rationale: The most appropriate response is "Many of the health services are given free, but we people pay for them just the same through our taxes." This response acknowledges the fact that public health services are funded by taxpayers, even though they may be perceived as free by the public. It highlights the connection between government funding and the provision of health services, emphasizing that these services are not truly free but are paid for through taxes. It also addresses the misconception that these services are entirely free without any costs involved.
