Correct Answer: C

Rationale: The correct answer is C: Systematic sampling. Nurse Sandy is adopting systematic sampling by selecting every third patient with MI after a random start. This method ensures equal chance of selection for each patient and maintains randomness. In contrast, simple random sampling (A) entails each patient having an equal chance of being selected independently. Stratified sampling (B) divides patients into groups based on certain characteristics, which is not the case here. Cluster sampling (D) involves grouping patients and selecting entire groups, which is different from the individual selection in this scenario.

Correct Answer: C

Rationale: The correct answer is C: Meningitis. The patient's symptoms of severe headache, photophobia, neck stiffness, nuchal rigidity, and positive Kernig and Brudzinski signs are classic signs of meningitis. Meningitis is an inflammation of the meninges surrounding the brain and spinal cord, leading to these specific neurological symptoms. Migraine headache (A) typically presents with a throbbing headache, nausea, and sensitivity to light and sound, but does not typically cause neck stiffness or positive meningeal signs. Cluster headache (B) is characterized by severe unilateral headache with autonomic symptoms like tearing or nasal congestion, but does not typically cause neck stiffness or positive meningeal signs. Subarachnoid hemorrhage (D) presents with sudden severe headache often described as "the worst headache of my life," and may cause neck stiffness, but typically does not present with photophobia or positive meningeal signs like Kernig and Brudzinski signs.

Correct Answer: C

Rationale: The correct answer is C: Nasal polyps. Nasal polyps are benign growths that form in the nasal cavity and sinuses, leading to symptoms such as chronic nasal congestion, hyposmia, and anosmia. The presence of polypoid masses seen on nasal endoscopy is characteristic of nasal polyps. Rationale: 1. Chronic nasal congestion, hyposmia, and anosmia are common symptoms of nasal polyps. 2. Nasal endoscopy revealing polypoid masses confirms the presence of nasal polyps. 3. Allergic rhinitis may cause nasal congestion but does not typically present with polypoid masses. 4. Chronic sinusitis can cause nasal congestion but is usually associated with inflammation of the sinuses, not just polypoid masses. 5. A deviated nasal septum can lead to nasal congestion but does not typically cause polypoid masses obstructing the nasal cavity and sinuses.

Correct Answer: D

Rationale: The correct answer is D: Inductive process. Qualitative research typically involves an inductive approach, where researchers gather data, analyze patterns, and develop theories or hypotheses based on the observed data. This allows for exploration and discovery of new insights. A) Deductive process is not a characteristic of qualitative research, as deductive reasoning involves starting with a hypothesis and testing it with data. B) Fixed research design is not common in qualitative research, which often uses flexible and adaptive designs to accommodate emergent findings. C) Control over the context is not a key characteristic of qualitative research, as it often involves studying real-world settings with natural contexts rather than controlled environments. In summary, the inductive process is a key characteristic of qualitative research as it allows for exploration and theory development based on observed data, distinguishing it from deductive approaches, fixed designs, and controlled contexts.

Correct Answer: B

Rationale: The correct answer is B: Prevents postpartum hemorrhage. Methylergonovine maleate is a uterotonic medication used to prevent and treat postpartum hemorrhage by causing strong uterine contractions, which help to control bleeding after delivery. It is not used to reduce lochia drainage (choice A), decrease uterine contractions (choice C), or maintain normal blood pressure (choice D). By understanding the pharmacological action of methylergonovine maleate in preventing postpartum hemorrhage, we can confidently select choice B as the correct answer.
