Correct Answer: C

Rationale: In cases where restraints are considered necessary for a patient, it is crucial to communicate effectively with both the patient and their family about the reasons for this decision. This helps ensure that all parties involved understand the necessity of restraints and are informed about the potential risks and benefits. Option A, securing restraints to the bed rails on all extremities, is not appropriate as it does not involve proper communication or ethical considerations. Option B, notifying the physician that restraints have been placed properly, overlooks the importance of patient and family involvement in decision-making. Option D, positioning the head of the bed at a 45-degree angle, is unrelated to the use of restraints and does not address the situation at hand.

Correct Answer: B

Rationale: The correct answer is to consider the possibility of self-harm during the assessment process. This is crucial because unless the client is first assessed for self-harm or suicide potential, the necessary degree of vigilance in the client's environment may not be observed. While understanding the meaning of current stressors is important for treatment planning, ensuring the client's safety takes precedence. Motivation to participate in treatment and the presence of alcohol or other drug use are also important aspects to assess but ensuring the client's safety is the top priority in this scenario.

Correct Answer: B

Rationale: In this scenario, the patient's symptoms of shortness of breath (SOB) and weakness in the lower extremities, along with a history of hyperlipidemia and hypertension, are suggestive of a myocardial infarction (MI). It is important to note that MI can present with a variety of symptoms, including those affecting the respiratory system and muscle weakness. Choices A, C, and D are incorrect because the patient's symptoms are more indicative of a myocardial infarction rather than congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), or peripheral vascular disease (PVD).

Correct Answer: A

Rationale: The correct answer is 'Hypotension and Angina.' Norvasc is a medication known to cause hypotension (low blood pressure) and angina (chest pain) as side effects. These side effects are important for the patient to watch out for as they can indicate potential issues related to the medication. Choice B ('Hypertension') is incorrect as Norvasc is actually used to treat hypertension, not cause it. Choice C ('Lower extremity edema') is not a common side effect of Norvasc. Choice D ('Peripheral sensory loss and SOB') is not typically associated with Norvasc's side effects.

Correct Answer: D

Rationale: A combined low PO2 and low SAO2 indicates hypoxia. The pH, PCO2, and HCO3 are normal. ABGs are not necessarily altered in TB or pleural effusion. In pneumonia, the PO2 and PCO2 might be low because hypoxia stimulates hyperventilation, but the best analysis in this case is hypoxia due to the combination of low PO2 and low SAO2.
