A patient presents with sudden onset of severe vertigo, nausea, vomiting, and nystagmus. The patient reports a recent upper respiratory tract infection. Which of the following conditions is most likely responsible for this presentation?

Correct Answer: A

Rationale: The sudden onset of severe vertigo, nausea, vomiting, and nystagmus in a patient with a recent upper respiratory tract infection is highly suggestive of vestibular neuritis. Vestibular neuritis is typically caused by inflammation of the vestibular nerve, often following a viral infection such as an upper respiratory tract infection. This condition presents with acute, severe, continuous vertigo without associated hearing loss. The presence of nystagmus, along with the absence of hearing loss, helps differentiate vestibular neuritis from Meniere's disease (which typically presents with episodic vertigo, hearing loss, and tinnitus) and acoustic neuroma (which presents with gradual onset of symptoms including unilateral hearing loss, tinnitus, and imbalance). Benign paroxysmal positional vertigo (BPPV) typically presents with brief episodes of vertigo triggered by specific head movements, rather than the continuous vertigo seen in this case.

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: 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: A

Rationale: When a nurse involves well-being in her definition of health, it indicates a holistic approach that considers not only physical health but also emotional, mental, and social aspects of well-being. In the context of a family confronting the imminent death of a family member, the primary concern of the nurse would be to focus on reinforcing the need for the whole family to adapt to the impending death. This involves providing emotional support, facilitating communication, addressing coping mechanisms, and assisting the family in coming to terms with the situation. By emphasizing the importance of the whole family adapting to the imminent death, the nurse can help promote holistic well-being for the family during this challenging time.

Correct Answer: D

Rationale: When administering Rilutek (riluzole), the medication should be taken with food. This is because taking Rilutek with food helps to reduce the likelihood of experiencing stomach upset as a side effect. Administering the medication on an empty stomach may increase the risk of gastrointestinal issues such as nausea, vomiting, or stomach pain. Therefore, it is recommended to administer Rilutek with food to ensure better tolerability for the patient.

Correct Answer: D

Rationale: The patient mentioned in the scenario presents with delayed puberty, short stature, and a childlike appearance. These symptoms are indicative of growth hormone deficiency (GHD). GHD is a condition where the pituitary gland does not produce enough growth hormone, which is crucial for normal growth and development.

Correct Answer: B

Rationale: In a stratified sampling method, the population is divided into subgroups or strata based on certain characteristics that are relevant to the research objective. This allows for representation from each subgroup in the sample, ensuring that different segments of the population are taken into account.

Correct Answer: A

Rationale: A nurse can be charged with negligence when they give the patient the wrong medication. Negligence in healthcare typically refers to a situation where a healthcare provider fails to provide a standard level of care, resulting in harm to the patient. Giving the wrong medication can lead to serious consequences for the patient, including adverse reactions, worsening of the condition, or even death. It is a clear violation of the duty of care that a nurse owes to their patients, and such a mistake can have legal and professional repercussions for the nurse.

Correct Answer: C

Rationale: The described presentation of a yellowish-white spot on the cornea with a ring of inflammation, along with branching, filamentous opacities extending from the corneal lesion, is characteristic of fungal keratitis. Fungal keratitis typically presents with these specific features on clinical examination.
