Correct Answer: D

Rationale: The vastus lateralis is the preferred site for IM injections in infants under 1 year of age because it is well developed and easily accessible compared to other muscle groups. The ventrogluteal and deltoid sites are not typically used for infants due to muscle development and size. The dorsogluteal site is not recommended for infants or young children due to its proximity to major nerves and blood vessels.

Correct Answer: D

Rationale: The correct answer is to have naloxone available in case of respiratory depression. Morphine is an opioid that can lead to respiratory depression, especially in higher doses. Naloxone is the antidote for opioid overdose and should be readily accessible when administering morphine to reverse respiratory depression if it occurs. Instructing the client to take a deep breath during administration (choice A) is not directly related to ensuring safety in this scenario. Administering the medication over 30 seconds (choice B) may help with the comfort of the client but does not address the potential risk of respiratory depression. Verifying the client's pain level (choice C) is important but not the primary action to ensure safety when administering morphine.

Correct Answer: B

Rationale: The correct answer is B: Decreased respiratory rate. In clients with COPD, especially when receiving oxygen therapy, a decreased respiratory rate is indicative of oxygen toxicity. This occurs because their respiratory drive is often dependent on low oxygen levels. Oxygen saturation of 94% is within an acceptable range and does not necessarily indicate oxygen toxicity. Wheezing is more commonly associated with airway narrowing or constriction, while peripheral cyanosis is a sign of decreased oxygen levels in the peripheral tissues, not oxygen toxicity.

Correct Answer: C

Rationale: In a thyroid storm, which is a severe complication of hyperthyroidism, hypertension is an expected finding. Other common manifestations include tachycardia, hyperthermia, and agitation. Hypothermia (choice A) is not expected in a thyroid storm as the body temperature is usually elevated due to increased metabolic rate. Bradycardia (choice B) is not typical in a thyroid storm; instead, tachycardia is more common. Lethargy (choice D) is not a typical finding in a thyroid storm, as clients are usually agitated due to excess thyroid hormone levels.

Correct Answer: D

Rationale: The correct answer is D: 'You may experience diarrhea with this medication.' Diarrhea is a common side effect of metformin, particularly when initiating the medication. It is important for clients to be aware of this potential side effect. Option A is incorrect because metformin is usually taken with meals to reduce gastrointestinal side effects. Option B is not directly related to metformin use. Option C is incorrect as muscle pain is not a common side effect of metformin and does not warrant stopping the medication.
