Correct Answer: C

Rationale: The nurse should always keep Tensilon (Edrophonium) at the bedside of a client with myasthenia gravis. Tensilon is a fast-acting cholinesterase inhibitor that can be used for the diagnosis and emergency treatment of myasthenia crisis. It helps improve muscle strength temporarily by increasing the levels of acetylcholine at the neuromuscular junction. Administering Tensilon can help differentiate between a myasthenic crisis (marked improvement in muscle strength) and a cholinergic crisis (no improvement or worsening of muscle weakness). Keeping Tensilon at the bedside allows for prompt administration in case of a myasthenic crisis.

Correct Answer: A

Rationale: The priority nursing intervention for a woman in active labor diagnosed with postpartum hemorrhage (PPH) due to uterine atony is to massage the uterus to promote contraction. Uterine massage helps to stimulate uterine muscle tone and contraction, which can help control bleeding by reducing the size of blood vessels and promoting hemostasis. It is important to address the uterine atony promptly to prevent further blood loss and stabilize the patient's condition. Other interventions such as blood transfusion, administering antibiotics, and elevating the mother's legs can be considered based on the patient's response to the initial intervention of uterine massage.

Correct Answer: D

Rationale: Ella's feeling of joining Lory in heaven is best categorized as suicidal ideation. Suicidal ideation refers to thoughts or fantasies about dying, including thoughts of one's own death or thoughts of wanting to harm oneself. In this scenario, Ella is not explicitly expressing any immediate intent to harm herself or others, nor is she exhibiting paranoia or making a direct threat. Instead, her mention of joining Lory in heaven suggests that she is contemplating the idea of death, which falls under the category of suicidal ideation. It is essential to take such thoughts seriously and seek appropriate help and support for the individual experiencing them.

Correct Answer: B

Rationale: Oxybutynin is a medication commonly used for the management of overactive bladder (OAB) symptoms such as urinary urgency and frequency. It belongs to a class of medications known as anticholinergics, which work by relaxing the bladder muscles and reducing bladder spasms. By doing so, it helps to decrease the symptoms of OAB, including frequent urination, sudden urges to urinate, and leakage. Oxybutynin can be taken orally in tablet form, as a transdermal patch, or as a gel, providing various options for patients based on their preferences and needs. Overall, oxybutynin is an effective treatment option for individuals experiencing overactive bladder symptoms.

Correct Answer: C

Rationale: Placenta previa is a condition in pregnancy where the placenta implants low in the uterus, partially or completely covering the cervix. This can lead to painless, bright red vaginal bleeding in the third trimester. However, in some cases, placenta previa can also present with sudden onset of severe lower abdominal pain and signs of shock, such as syncope, pallor, and abdominal distention due to concealed bleeding. In severe cases, the bleeding can be significant and life-threatening for both the mother and the baby. It is important to promptly diagnose and manage placenta previa to prevent complications.
