Correct Answer: D

Rationale: During the active phase of labor, a cervical dilation of 6 cm and regular contractions lasting 60 seconds each, occurring every 3 minutes indicate good progress in labor. The nurse should continue to monitor the progress closely by assessing the mother's vital signs, fetal heart rate, and the pattern of contractions. It is important to provide support and encouragement to the mother, continue with comfort measures, and be prepared to assist with the delivery when the cervix is fully dilated. This stage of labor is focused on active dilation and effacement of the cervix, and it is not yet time for the mother to push or for the nurse to administer oxytocin to augment labor.

Correct Answer: A

Rationale: The clinical presentation of fever, chills, headache, and myalgia after a trip to sub-Saharan Africa is highly indicative of malaria. Specifically, the presence of intraerythrocytic ring forms and trophozoites on blood smear examination points towards Plasmodium falciparum as the most likely causative agent. Plasmodium falciparum is the most deadly of the Plasmodium species that cause malaria and is responsible for the majority of severe malaria cases worldwide. It is transmitted through the bite of infected Anopheles mosquitoes. Treatment for Plasmodium falciparum infection usually involves antimalarial medications such as artemisinin-based combination therapies.

Correct Answer: C

Rationale: The salivary glands are responsible for the production of saliva, which aids in lubricating the oral cavity and initiating the digestion of carbohydrates. Saliva contains enzymes that begin the digestive process by breaking down carbohydrates into simpler sugars. The liver is involved in the production of bile, which aids in the digestion and absorption of fats. The gallbladder stores bile produced by the liver, which is released into the small intestine. The pancreas produces digestive enzymes that are released into the small intestine to aid in the digestion of proteins, fats, and carbohydrates.

Correct Answer: A

Rationale: Generalized seizures involve both hemispheres of the brain and can present with various manifestations. The typical features of generalized seizures include loss of consciousness, dilated pupils, and muscular stiffening. These seizures may also involve other symptoms such as tonic-clonic movements, convulsions, and postictal confusion. Jerking movements of all extremities (option B) are more characteristic of tonic-clonic seizures, a subtype of generalized seizures. Facial grimace with patting and smacking (option C) may be seen in focal seizures originating from a certain area of the brain. A vacant stare with a brief loss of consciousness (option D) is more typical of absence seizures rather than generalized seizures.

Correct Answer: B

Rationale: In this scenario, the physician-specialist assessed the patient and determined that an immediate sonogram is needed for the medical condition. An intervention is a specific action taken in response to a medical need or condition. Ordering an immediate sonogram falls under the category of an intervention because it involves a timely and targeted diagnostic procedure to address the medical situation identified by the physician. The other options (A. Operation Room, C. Laboratory, D. CT scan) do not accurately represent the specific action of ordering a sonogram in response to the medical condition assessed by the physician.
