The practical nurse (PN) is preparing cefazolin 400 mg IM for a client with a gram-positive infection. The available vial is labeled, "Cefazolin 1 gram," and the instructions for reconstitution state, for IM use, add 2 mL sterile water for injection. Total volume after reconstitution is 2.5 mL. After reconstitution, how many mL should be administered to the client? (Enter numeric value only. If rounding is required, round to the whole number, nearest tenths/hundredth).

Choice A rationale:

Objective data. Rationale: Objective data are observable and measurable facts obtained through physical examination or diagnostic tests. The statement incorrectly labels the data as objective when it is, in fact, based on the client's feelings and perceptions, making it subjective.

Choice B rationale:

Subjective data. Rationale: Subjective data are information provided by the client, including their feelings, perceptions, and experiences. The statement correctly labels the data as subjective, as it reflects the client's report of thirst and hunger.

Choice C rationale:

Primary data. Rationale: Primary data are original data collected directly from the source, such as a client's medical history or interview. However, this classification does not address the nature of the data as being subjective or objective, so the statement does not provide a complete answer.

Choice D rationale:

Secondary data. Rationale: Secondary data are data obtained from sources other than the client, such as medical records or research studies. Similar to choice C, this classification does not address the nature of the data as being subjective or objective.

Choice A rationale:

"Phobias are characterized by persistent and irrational fear" (Choice A) is an accurate statement. Phobias are defined by the presence of an intense and irrational fear of a specific object or situation. This fear is persistent and often leads to avoidance behaviors, which can significantly impact the individual's daily life.

Choice B rationale:

"Phobias can be caused by biological factors only" (Choice B) is an inaccurate statement. Phobias can have various causes, including both biological and psychological factors. While there may be genetic predispositions to certain phobias, psychological factors, such as traumatic experiences or learned behaviors, can also contribute to the development of phobias.

Choice C rationale:

"Phobias can be diagnosed based on physical symptoms" (Choice C) is an inaccurate statement. Phobias are typically diagnosed based on the individual's reported symptoms, such as intense fear and avoidance behaviors. There are no specific physical symptoms that directly indicate the presence of a phobia.

Choice D rationale:

"Phobias can be managed with medication alone" (Choice D) is an inaccurate statement. Medication alone is not considered the primary treatment for phobias. While medications like selective serotonin reuptake inhibitors (SSRIs) or benzodiazepines may be prescribed to alleviate anxiety symptoms, the most effective treatment for phobias is psychotherapy, particularly exposure therapy or cognitive-behavioral therapy. These therapies address the root causes of the phobia and help individuals learn to manage their fear.
