Correct Answer: C

Rationale: The correct answer is C because insulin needles should be disposed of after a single use to prevent infection. Reusing the same needle for three days can lead to infection and is not a safe practice. Choices A, B, and D demonstrate good understanding of insulin administration and diabetes management, so they do not indicate a need for further teaching.

Correct Answer: A

Rationale: When a patient reports an inability to clear nasal passages, the appropriate action for the nurse to take is to use gentle suction to prevent tissue damage. Suctioning helps remove excess mucus or secretions without causing harm to the nasal tissues. Instructing the patient to blow their nose forcefully (Choice B) may exacerbate the issue and cause discomfort or injury. Placing a dry washcloth under the nose (Choice C) is not an effective intervention for clearing nasal passages. Inserting a cotton-tipped applicator into the back of the nose (Choice D) is not recommended as it can be invasive and may cause injury or discomfort to the patient.

Correct Answer: A

Rationale: The correct answer is A: Trying to increase independence. Toddlers around the age of 2 often exhibit behaviors like temper tantrums and saying 'no' as they are asserting their independence and autonomy. This behavior is a normal part of their developmental stage where they are starting to explore and assert their own preferences and desires. Choice B, developing a sense of trust, is more relevant to infants during the trust vs. mistrust stage. Choice C, establishing a new identity, is typically associated with adolescence and identity formation. Choice D, attempting to master a skill, is more indicative of a child trying to learn and develop new abilities rather than the behavior described in the scenario.

Correct Answer: C

Rationale: The correct answer is C: Friction. The amount of friction is crucial in effective hand hygiene to remove microorganisms. Rubbing hands together with friction helps to dislodge and remove dirt, oils, and microorganisms. While temperature and soap are important factors in hand hygiene, the mechanical action of friction plays a more significant role in physically removing contaminants. Time is also important in hand hygiene practice, but without adequate friction, the effectiveness of the process is compromised.

Correct Answer: D

Rationale: Hypotension is a critical finding that should be reported immediately in a client with acute pancreatitis as it may indicate severe complications such as hemorrhage or shock. While elevated serum lipase level, severe abdominal pain, and nausea/vomiting are common manifestations of acute pancreatitis, hypotension is a more urgent sign requiring immediate attention to prevent further deterioration. Hypotension can be a sign of significant fluid loss, hemorrhage, or sepsis, which are potentially life-threatening conditions that need prompt intervention. Elevated serum lipase levels, severe abdominal pain, and nausea/vomiting are important in the assessment of pancreatitis but do not indicate the same level of immediate danger as hypotension does.
